If you load an element on your page after page load (i.e. via AJAX), basic JQuery event listeners such as this:

$(".my-selector").click(function(event) {
...
});

won't work, because that event listener only listens to elements that appear upon completion of page load. To catch elements introduced later via AJAX, use the live handler:

$(".my-selector").live('click', function(event) {
...
});

That will attach the 'click' event handler to all selected elements, even ones inserted into the DOM after page load. See the JQuery docs for more info: http://api.jquery.com/live/
