First jQuery extension assistance

I'm fed up of writing the same code over and over again, so trying to get to grips with doing my own jQuery extension to simplify and replace some of the most common repetitions.

So after reading a few webpages, a few chapters, and asking a few questions on here, Ive come up with the following code:-
	(function( $ ) {
		$.fn.tcDialogue = function(options) {
			$('body').append("hello");
			
            var closeDialogue = function(other_args) {
                alert("I would close if I was written");
            };
		};
	}(jQuery));

	$(document).ready(function (){
		var testDialogue = tcDialogue();
		testDialogue.closeDialogue();
    });

Open in new window


Which should (as far as I'm aware) put 'hello' into the body, and then display an alert, however all I get from my browser is 'tcDialogue' is not declared, so I'm obviously doing something wrong, but does anyone have any ideas as to what I've done wrong?

Thank you in advance

This is what you might be looking for:
http://jsfiddle.net/BvssN/

(function ($) {
    $.fn.tcDialogue = function (options) {
        this.append("hello");
        
        var closeDialogue = function (other_args) {
            alert("I would close if I was written");
        };
        
        return {
            closeDialogue: closeDialogue
        };
    };
}(jQuery));

$(document).ready(function () {
    var testDialogue = $('body').tcDialogue();
    testDialogue.closeDialogue();
});

I saw that you're planning to use options also.
Here's an example that uses it:
http://jsfiddle.net/BvssN/1/
(function ($) {
    $.fn.tcDialogue = function (options) {
        var defaultOptions = {
            name: 'John Doe'
        };
        var options = $.extend({}, defaultOptions, options);
        
        this.append("hello " + options.name);
        
        var closeDialogue = function (other_args) {
            alert("I would close if I was written");
        };
        
        return {
            closeDialogue: closeDialogue
        };
    };
}(jQuery));

$(document).ready(function () {
    var testDialogue = $('div').tcDialogue();
    testDialogue.closeDialogue();
    var testDialogue = $('div').empty().tcDialogue({ name: 'Maria' });
});
