Working out why an event is not fired
<p>I have a draggable which is using over within a draggable :</p>

<p>But the event is not firing, it is part of a much larger jQuery file and it seems to work every time I add it to jsFiddle. Are there any debug tools/methodologies I can use to figure out why this event is not firing ? </p>

<pre><code>    over: function(event, ui) {
     console.log('in over');
    }
</code></pre>
