jquery: How do I use click event to modify an element, then different click event to modify the original element?

I'm very new at javascripting and jquery but I've got the basics down. I need help with using jquery click functions to modify elements. I am using a jquery plugin (dataTables) to create a sortable table. That part was easy. The table is initially hidden, and I want the user to be able to click on one of the links on my page to display a filtered version of the table. Ex: click on link #1 - display table filtered for keyword#1, click on link #2 - display table filtered for keyword#2, etc.

I was able to accomplish this using jquery click events, but I found that after the filtered table displays, if one of the headers is clicked to sort on a column, then the entire original table comes back. I couldn't find anything in the plugin's documentation about this, so I had to find an alternative.

I was able to do the following: run the dataTables method on my original master table (with sort option: false), create (and hide) the table, onclick - filter that table on a keyword, then run the dataTables method again on the filtered table (with sort option: true), then show the table. This is probably not the right way of fixing my problem, but it does work...now this table only contains the data that I filtered on and the user can sort on headers.

Here is my real problem - when I pass the filtered table through the dataTables method again, it seems I am somehow permanently attaching that function/method to my filtered table. Ex - when I click on link#1, I get my table filtered for keyword#1, but if I click on link #2, I get a 'no results found'.  It seems that it is trying to filter the already filtered table?

Please have a look...I hope you can help!

table id = "listings"
link id = "showCelina"
link id = "showColdwater"

plugin: dataTable
additional function for plugin: fnFilter('string') - is *supposed to* filter the table for the string and redraw the table
this script will allow you to click on either link and display the table filtered for the keyword associated with that link - but on clicking a header, the entire table comes back...is there something i'm missing?
 
<script type="text/javascript" charset="utf-8">
var filterCelina;
var filterColdwater;
$(document).ready(function() {
	filterCelina = filterColdwater = $('#listings').dataTable( {
		"iDefaultSortIndex": 0,
		"sDefaultSortDirection": "asc",
		"bPaginate": false,
		"bLengthChange": false,
		"bFilter": false,
		"bInfo": false,
		"bAutoWidth": false,
		"aoData": [{ "sType": "html" },null,null]
		} );
$('#listings').hide();
$('#showCelina').click(function () {
	filterCelina.fnFilter( 'Celina' );
	filterCelina.show();
	} );
$('#showColdwater').click(function () {
	filterColdwater.fnFilter( 'Coldwater' );
	filterColdwater.show();
	} );
} );
</script>
 
 
otherwise...this script will run the filtered tables back through dataTable method taking care of the earlier issue, but it will only work the first time I click on any link. if i click on another link, I get 'no matching records found'
 
<script type="text/javascript" charset="utf-8">
var filterCelina;
var filterColdwater;
$(document).ready(function() {
	filterCelina = filterColdwater = $('#listings').dataTable( {
		"iDefaultSortIndex": 0,
		"sDefaultSortDirection": "asc",
		"bPaginate": false,
		"bLengthChange": false,
		"bFilter": false,
		"bSort": false,
		"bInfo": false,
		"bAutoWidth": false,
		"aoData": [{ "sType": "html" },null,null]
		} );
$('#listings').hide();
$('#showCelina').click(function () {
	filterCelina.fnFilter( 'Celina' );
	filterCelina.dataTable( {
		"iDefaultSortIndex": 0,
		"sDefaultSortDirection": "asc",
		"bPaginate": false,
		"bLengthChange": false,
		"bFilter": false,
		"bSort": true,
		"bInfo": false,
		"bAutoWidth": false,
		"aoData": [{ "sType": "html" },null,null],
		"aoData": [{ "sWidth": "360px" },{ "sWidth": "252px" },{ "sWidth": "108px"}]
		} );
	filterCelina.show();
	} );
$('#showColdwater').click(function () {
	filterColdwater.fnFilter( 'Coldwater' );
	filterColdwater.dataTable( {
		"iDefaultSortIndex": 0,
		"sDefaultSortDirection": "asc",
		"bPaginate": false,
		"bLengthChange": false,
		"bFilter": false,
		"bSort": true,
		"bInfo": false,
		"bAutoWidth": false,
		"aoData": [{ "sType": "html" },null,null],
		"aoData": [{ "sWidth": "360px" },{ "sWidth": "252px" },{ "sWidth": "108px"}]
		} );
	filterColdwater.show();
	} );
} );
</script>

When bFilter = false; it is hardcoded not to re-filter in all of the functions.
<script type="text/javascript" charset="utf-8">
var filterCelina;
var filterColdwater;
$(document).ready(function() {
        filterCelina = filterColdwater = $('#listings').dataTable( {
                "iDefaultSortIndex": 0,
                "sDefaultSortDirection": "asc",
                "bPaginate": false,
                "bLengthChange": false,
                "bFilter": true,
                "bInfo": true,
                "bAutoWidth": false,
                "aoData": [{ "sType": "html" },null,null]
                } );
$('#listings').hide();
$('#listings_filter').hide();
$('#showCelina').click(function () {
        filterCelina.fnFilter( 'Celina' );
        filterCelina.show();
        } );
$('#showColdwater').click(function () {
        filterColdwater.fnFilter( 'Coldwater' );
        filterColdwater.show();
        } );
} );
</script>

Oh how simple! I could have saved myself a few hours of tinkering if I had though of that earlier. I just had the filter as false so the search box wouldn't show, but I see that I can easily hide the search box with jquery. Thanks for your quick and easy solution!
