title: Dojo tab is not loading external html
body: <p>When I click the second tab I want the callrecords.html code to be loaded but it isn't loading anything and the pane stays blank.  I'm somewhat of a noob and can't seem to figure out why this is happening.</p>
  
  <p>Also a side question.  Why do some code samples say dojoType and others use data-dojo-type.</p>
  
  <pre><code>&lt;body class="tundra"&gt;
  
      &lt;div class="formContainer" dojoType="dijit.layout.TabContainer" &gt;
  
          &lt;div dojoType="dijit.layout.ContentPane" title="Advanced Search"&gt;
              &lt;label for="first_name"&gt;First Name:&lt;/label&gt;
              &lt;input type="text" name="first_name" id="first_name" 
                     size="30" /&gt;&lt;br/&gt;
              &lt;label for="last_name"&gt;Last Name:&lt;/label&gt;
              &lt;input type="text" name="last_name" id="last_name" 
                     size="30" /&gt;&lt;br/&gt;
              &lt;label for="middle_initial"&gt;Middle Initial:&lt;/label&gt;
              &lt;input type="text" name="middle_initial" id="middle_initial" 
                     size="1" /&gt;&lt;br/&gt;
          &lt;/div&gt;
  
          &lt;div dojoType="dijit.layout.ContentPane" title="Call Records" data-dojo-props='href:"modules/content_panes/callrecords.html", refresnOnShow:true'&gt;&lt;/div&gt;
  
          &lt;div dojoType="dijit.layout.ContentPane" title="Phones"&gt;
              &lt;label for="home_phone"&gt;Home Phone:&lt;/label&gt;
              &lt;input type="text" name="home_phone" id="home_phone" 
                     size="30" /&gt;&lt;br/&gt;
              &lt;label for="work_phone"&gt;Work Phone:&lt;/label&gt;
              &lt;input type="text" name="work_phone" id="work_phone" 
                     size="30" /&gt;&lt;br/&gt;
              &lt;label for="cell_phone"&gt;Cell Phone:&lt;/label&gt;
              &lt;input type="text" name="cell_phone" id="cell_phone" 
                     size="30" /&gt;&lt;br/&gt;
          &lt;/div&gt;
  
      &lt;/div&gt;
  
  &lt;/body&gt;

  <p>callrecords.html</p>
  
  <pre><code>&lt;h1&gt;Tab 2&lt;/h1&gt;
  
  &lt;p&gt;I am tab 2. I was loaded externally as well.&lt;/p&gt;
