JQuery :: Attaching Multiple Event Handlers?

I have a piece of javascript which does not work as intended. The code is:

var v = document.getElementById('ReportViewer1');
if (v) { v.ClientController.CustomOnReportLoaded = endPoll;
}

The endPoll event handler should be added to the list of event handlers for CustomOnReportLoaded. In the code about, it removes all other event handlers and just adds itself. Looking through JQuery i found:

$('#foo').bind('click', function() {
alert($(this).text());
});

this will add the new event handler to the collection of event handlers already attached to the click event.how do I select the ClientController through JQuery's selectors?
