Jquery .on with doubleclick event
<p>Why would this work :</p>

<pre><code>$(document).on("dblclick", "#areaA tr:has(td)", function (){
     //code here
 }
</code></pre>

<p>and this does not</p>

<pre><code>$("#areaA tr:has(td)").on('dblclick', function(e) {
    //Code here
}
</code></pre>

<p>I'm following the example on the jquery documentation page exactly, but my double click does not fire.  When I do it the first way, it works, but seems like it fires the event twice.</p>

<p>This is in the context of a Kendo UI grid.</p>

<p>Is there really a difference between these two pieces of code?</p>
