jQuery: When entering text in input field, doesn't enable the button
<p>I have a jsfiddle <a href="http://jsfiddle.net/hhimanshu/9kKXX/" rel="nofollow">here</a>.</p>

<p><em><strong>jQuery</em></strong></p>

<pre><code>$(function() {
    //var input = $('form :input[type="text"]')
    $('form :input[type="text"]').live('keyup', function() {
        $('form .create-playlist-button')
            .attr('disabled', $('form :input[type="text"]').val().length == 0);
    });
});
</code></pre>

<p><strong>Needed</strong>  </p>

<ul>
<li><p>When I start entering the data in the textbox, create should be enabled.</p></li>
<li><p>When I remove all text from the textbox, create should be disabled.</p></li>
</ul>

<p>I am very new to jQuery and this thing is not working for me.</p>
