Initiate method onchange on input
<p><a href="http://jsfiddle.net/hVSTJ/" rel="nofollow">http://jsfiddle.net/hVSTJ/</a></p>

<p>Why when we run $("#navTop").val("x");​, we don't get alert message? That's what I need. I need to initiate that method everytime input's value changes. Can't figure it out how.</p>
