title: Dojo and unregistering widgets
body: <p>I am new to the Dojo Toolkit. I'm getting the error</p>
  
  <pre><code>Tried to register widget with id=myButton but that id is already registered
  </code></pre>
  
  <p>whenever I try to load dojo content twice (meaning I load HTML content through jQuery.Load into a container div). Is there a way of unregistering already registered widgets in dojo? I've seen some examples, but I don't really get them working.</p>
  
  <p>My button:</p>
  
  <pre><code>&lt;button dojoType="dijit.form.Button" id="myButton"&gt;button&lt;/button&gt;
  </code></pre>
