Trying to animate with on change
<p>I am trying to animate the width of something when the .change() function is called, but it doesn't seem to be working.</p>

<p>Any idea why?</p>

<p>Here is my code:</p>

<pre><code>$(document).ready(function(){
    $('#code').change(function(){
        //on change animate a width of +16px increase.
        $(this).animate({width: '+=16'});
    });
});
</code></pre>

<p>Here is a js fiddle with the issue recreated: <a href="http://jsfiddle.net/BUSSX/" rel="nofollow">http://jsfiddle.net/BUSSX/</a></p>
