title: Dojo - How to refresh combobox with updated ItemFileReadStore data
body: <p>I changed ItemFileReadStore for combobox in Dojo. 
  My code looks something like</p>
  
  <pre><code>    &lt;span dojoType="dojo.data.ItemFileReadStore"
                  jsId="comboStore"
                  data="transformData"&gt;
              &lt;select dojoType="mywidget.DropDown" id="transformCombo" value="" store="comboStore" searchAttr="name" name="state" maxHeight="100"/&gt;
  </code></pre>
  
  <p>My widget is similar to dojo combobox widget. I changed transformData but the combobox is not updated until the page is entirely reloaded again. Any idea?</p>
