Popup Window Click

[The Little Guy]

I am trying to test whether or someone clicks on the button or not in a popup window I tried this, but it doesn't work:

 

var mw = window.open("http://facebook.com/sharer/sharer.php?u="+window.location.toString(), 'facebook', 'status=0,toolbar=0,height=350,width=550,scrollbars=no,resizable=no');
$(mw.document).load(function(){
$(document).click(function(){
	alert("hi");
});
});

 

Is this even possible?
