Catching the Click on DOM/HTML/BODY event on the iPad

I'm using jQuery to detect a click on the DOM - or let's every click.

$(document).click(function(){
   alert("Click :-)");
});

This works pretty good in every browser except Safari for iPad/iPhone. I've also tried to apply the event on the html or body element - no way. How to detect a common click on the iPad/iPhone?

Best regards, Jim
