title: jQuery icheck plugin not working after being append
body: <p>I have ADD button and when I click it append the following:</p>
  
  <pre><code>&lt;div class="checkbox"&gt;
      &lt;label&gt;
         &lt;input type="checkbox"&gt; Sample
      &lt;/label&gt;
   &lt;/div&gt;  
  </code></pre>
  
  <p>to another div (class name .new-option-content). <strong><a href="http://jsfiddle.net/Lq07ysbq/2/" rel="nofollow">FIDDLE</a></strong></p>
  
  <p>I am using jquery icheck plugin to stylize the check boxes. But when I append I don't see icheck styling on the check boxes. why this can happen ? I call the  function properly but why it's not showing it's styling after append ?</p>
  
  <p>Any help will be appreciated.Thanks</p>
