Click handler stopped working in Alpha 2

Click handler stopped working in Alpha 2

I have this code:

$(document).ready(function() {
$(".ui-page-active #starttimerbutton").click(function() {
console.log("tap event!");
console.log(e);
stopTimer();
});
});

<div id="buttondiv">
      <button data-inline="true" id="starttimerbutton" data-theme="b" value="Stop Timer"></button>
</div>

This was working, but now it's not, what am I doing wrong? Thanks!
