jQuery - multiple event listeners for same button
<p>Say I have an button with an id:</p>

<p><code>&lt;input id='someButton' /&gt;</code></p>

<p>I want to attach an event listener on this button:</p>

<pre><code>$('#form').on('click', '#someButton', function() { 
   alert("My listener called"); 
</code></pre>

<p>});</p>

<p>However, unbeknownst to me, someone previously wrote an event listener for this very same button:</p>

<pre><code>$('#form').on('click', '#someButton', function() { 
   alert("Some other listener called"); 
});
</code></pre>

<p>I encountered some code that effectively does the same thing as above, and it seems like the first listener registered is the one that is used.  Am I correct in assuming jQuery will always call the first event listener registered on a specific id (and <em>only</em> that listener)?</p>
