How can I prevent a change event from being fired from a selected radio button?
<p>I'm trying to fire a change event for a selected group radio button but this event gets fired if I select an already selected radio button.  Can I prevent this from happening? </p>

<pre><code>$("input[type='radio']").mouseup(function(){
    ... 
}).change(function(){
    ...
});
</code></pre>

<p>HTML</p>

<pre><code>&lt;label class="radio"&gt;
    &lt;input type="radio" name="optionsRadios" id="optionsRadios1" value="option1" checked&gt;
            Option one
&lt;/label&gt;
&lt;label class="radio"&gt;
    &lt;input type="radio" name="optionsRadios" id="optionsRadios2" value="option2"&gt;
            Option two
&lt;/label&gt;
</code></pre>
