Form:has selector does not work on IE
<p>I am trying to use "form:has" selector which works on Chrome but not on IE.</p>

<p>Does anyone have any idea why it is not working on IE? (when pushing the Post button there should be an alert box)</p>

<p>Edited:</p>

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

<h2>JS:</h2>

<pre><code>  $(document).ready(function() {

    $(".comment-link").live('click',function() {
      return false;
    });

    $("#morefeeds-link").click(function () {
      return false;
    });
    // Form submittion - doesnt work
    $("form:has(.commentBtn)").live('submit',function () {
       alert("a");
      return false;
    });

    return false;
  });​
</code></pre>

<h2>HTML</h2>

<pre><code>&lt;form&gt;

  &lt;a href="#" class="comment-link" style="font-size:12px;"&gt;Comment&lt;/a&gt;

    &lt;table border="0" cellpadding="0" cellspacing="0"&gt;
      &lt;tr&gt;
        &lt;td valign="middle"&gt;
          &lt;input type="hidden" name="commentkey" value="1"&gt;
          &lt;input type="text" name="commenttext" class="commentfocus" value="Express your opinion"&gt;
        &lt;/td&gt;
        &lt;td valign="middle"&gt;&lt;input type="submit" class="commentBtn" value="Post"&gt;&lt;/td&gt;
      &lt;/tr&gt;
    &lt;/table&gt;

 &lt;/form&gt;
</code></pre>
