not :contains isn't working
<p>What did I do wrong? When I run this code, nothing is displayed.</p>

<p>The JavaScript code:</p>

<pre><code>var currentTime = new Date()
var month = currentTime.getMonth() + 1
var day = currentTime.getDate()
var year = currentTime.getFullYear()

$(".whocares:not(:contains('' + month + '/' + day + '/'+ year + ''))").remove();​
</code></pre>

<p>And the HTML:</p>

<pre><code>&lt;div class="whocares"&gt;hi&lt;/div&gt; &lt;div class="whocares"&gt;12/26/2012 i like cake two&lt;/div&gt; &lt;div class="whocares"&gt;hi&lt;/div&gt;
</code></pre>
