javascript - How to run a function from radio button mouseup event?

I'm trying to use a pair of radio buttons to start/stop an
automated horizontal scroller. I've tried several jquery techniques that I found on SO,
but I haven't been able to get them to
work.

Here's my latest
attempt:

$( "#radAutoScroll0"
            ).mouseup(function() {
 scrollTimer(); 
});
function
            scrollTimer(){
 if($("#radAutoScroll0").is(':checked')){
 //
            scroller code.....
 }
}


            class="scrollDiv">
             class="autoScrollLabel">Auto Scroll
             for="radAutoScroll0" class="labAutoScroll">
             name='radAutoScroll' id='radAutoScroll0' class="rad1" checked="checked"
            value='on'/>On
 
             class="labAutoScroll">
             id='radAutoScroll1' class="rad1" value='off'/>Off
