Jquery - Hitwise Tracking On ImageButton Click Event In ASP

I have an ImageButton setup, where in the OnInit event, I'm setting the Click event

btnJoinNow.Click += new ImageClickEventHandler(btnJoinNow_Click);

On the client-side, I have setup a jQuery click event which is to fire of a hitwise tracking event only when the button is pressed. The problem I'm having is that it seems that the button event is beating the javascript and not tracking. I need to put a pause of 1 sec before the imagebutton event fires server-side. I've tried the following, but always fires. I've also tried e.preventDefault(), but that just stops the postback altogether.

$("input[id$='btnJoinNow']").click(function(e) {
Spots.HitWise();
setTimeout(function(){
}, 5000);
});

EDIT: The only way I could get this to work, was by doing the following:

$("input[id$='btnJoinNow']").click(function(e) {
Spots.HitWise();
setTimeout(function(){
$("input[id$='btnJoinNow']").unbind('click').bind('click', function(e){});
}, 1000);
return false;
});

This then allows enough time for the HitWise event to track, then clears the click event and calls itself again.
