Not flipping Images For Some Reason, Mouseup not firing

Not flipping Images For Some Reason, Mouseup not firing

Can someone tell me why this request isn't working?  I click the LMB and move my mouse up and down and nothing works (Firebug also gives no errors)



[code]
    $("#filmviewer").mouseup(function(){
         alert("t");

    });


[/code]

html

[code]
<div  id="filmviewer" style="width:400px;">
<img src="pic_1.jpg" />
</div>
[/code]

The problem is when I click and mouseup over the image the alert("t")  does not fire.  what am I doing wrong?
