JQuery ajaxStart event not writing to ASP.net AJAX

Question

I have an asp.net page with a save button in the updates palette and contenttemplate. Saving works beautifully, but I'm trying to add a “wait” gif, while saving happens using jQuery, but the ajaxStart event doesn't fire. I set a simple catch, shown below:

        $(document).ajaxStart(function(){
            alert('starting');
        }).ajaxStop(function() {
            alert('done');
        });

When you click the Save button, warnings are not displayed. Is there a problem when trying to capture ASP.NET Ajax events, is asp executing some kind of funky type of Ajax calls that cannot be captured by jQuery?

Thanks, let me know if you have any ideas about this,

Mark.

    <script type="text/javascript">
        function pageLoad() {
            if (!Sys.WebForms.PageRequestManager.getInstance().get_isInAsyncPostBack()) {
                Sys.WebForms.PageRequestManager.getInstance().add_endRequest(AjaxEnd);
                Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(AjaxBegin);
            }
        }

        function AjaxEnd(sender, args) {
           alert("I am done...");
        }

        function AjaxBegin(sender, args) {
            alert("I am about to start...");
        }
   </script>
