on() method with select element not firing
<p>I'm using <code>jQuery 1.9.0</code> and I'm trying to trigger the <code>on()</code> method whenever an option is changed inside a select. It worked with <code>live()</code> but I think its probably something simple that I'm not seeing.</p>

<p>This is my HTML:</p>

<pre><code>&lt;select class="select_exercise"&gt;
    &lt;option class="option_exercise"&gt;Example 1&lt;/option&gt;
    &lt;option class="option_exercise"&gt;Example 2&lt;/option&gt;
&lt;/select&gt;
</code></pre>

<p>and my Script:</p>

<pre><code>$("option.option_exercise").on("change","option.option_exercise",function()
{
    alert("i am changing");
});
</code></pre>

<p>Here is <a href="http://jsfiddle.net/fNjL3/1/" rel="nofollow"><strong>the fiddle</strong></a></p>
