title: Select2 and Datetimepicker does not work in cloned div
body: <p>I clone div with jquery which contains textarea, select2 and datatimepicker.
  But cloned select2 and datetimepicker is not working.</p>
  
  <pre><code>&lt;div id= "myDiv"&gt;
      &lt;textarea id="myTextArea"&gt;&lt;/textarea&gt;
      &lt;select class="mySelect2"&gt;
         &lt;option value="1"&gt;1&lt;/option&gt;
         &lt;option value="2"&gt;1&lt;/option&gt;
      &lt;/select&gt;
      &lt;div class="date date-picker" data-date-format="dd.mm.yyyy"&gt;
          &lt;input type="text" readonly&gt;&lt;/div&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I also added  <code>$('.date-picker').datepicker();</code> and <code>$(".mySelect2").select2();</code> into my javascript code.</p>
  
  <pre><code>function create() {
      $("#myDiv  div:first").clone().find("textarea select input").each(function () {
          $(this).val('');
      }).end().appendTo("#myDiv");
  }
  </code></pre>
