This is what I did
function MakeListboxInput(intId, text, size) {
    // use UpdateSFValue or UpdateSFValueAndRefresh in your onchange event handler
    var input;
    if (text == "") {
        input = '<input id="isAOI" type="checkbox" checked="checked" value="true"  size="' + size + '" onclick="UpdateSFValue(' + intId + ',this.value)">Is AOI?';
    }
    else {
        input = '<input id="isAOI" type="checkbox" value="" size="' + size + '" onclick="UpdateSFValue(' + intId + ',this.value)">Is AOI?';
       
    }

    return input;
}

var bChecked = isAOI.checked;

alert(bChecked);

If you wanted a function to get this then you could do:

<script>
function cbCheck(oFld)
{
  alert(oFld.checked);
}
</script>

Then in your HTML:

<input type="checkbox" name="isAOI" value="" id="isAOI" onchange="cbCheck(this);">

jQuery test page : http://jsfiddle.net/F27HB/

$(document).ready(function() {

$(":checkbox[name='isAOI']").change(function() {
       var checkbox_Value = $(this).val();
       alert( checkbox_Value );
})

});

Here is what I have
var input = '<input type="text" name="special" value="' + text + '" size="' +size +'" onchange="UpdateSFValue(' + intId + ',this.value)">';

No matter if the checkbox is checked or unchecked it passes the default value to the UpdateSFValue method.

What are you trying to do here? The input you have shown is a text box. Can  you supply the code for UpdateSFValue()?

Sorry about that
var input = '<input id="isAOI" type="checkbox"  size="' + size + '" onchange="UpdateSFValue(' + intId +' ,this.value)">Is AOI?';

The UpdateSFValue method is something that is pretty specific to our system.
