title: label not clickable in jqtouch
body: <p>With following code I can not click on labels in jqtouch (on iphone simulator and iphone itself):</p>
  
  <pre><code>&lt;ul class="rounded"&gt;
    &lt;li&gt;
      &lt;label for="user_name"&gt;Name&lt;/label&gt;
      &lt;input type="text" name="user_name" id="user_name"/&gt;
    &lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>It is working well in safari, I have checked this also in demo of jquery-mobile and it is working on iphone simulator, so problem seams to be strictly jqtouch specific.</p>
