title: Form checkboxes not being displayed correctly second time shown
body: <p>I have a weird problem with a simple form with checkboxes..</p>
  
  <p>The first time it's shown it looks fine.. But then after navigating back to the previous page and be to it again - the ui is not updates resulting in plain checkboxes without jQuery mobile style..</p>
  
  <p>I've Googled like crazy and found a couple of hints like  .fieldcontain(); but it's doesn't work =(</p>
  
  <p>The data is being retrieved through knockout bindings..</p>
  
  <p>Any good ideas?</p>
  
  <p>Here's the code...</p>
  
  <pre><code>&lt;div id="searchCitiesPage" data-role="page" data-theme="a" class="page searchCities"&gt; 
  &lt;header data-role="header" data-theme="b"&gt;
  &lt;/header&gt;
  &lt;div data-role="content" class="content" data-theme="a"&gt;  
      &lt;script id="countyListTemplate" type="x-jquery-tmpl"&gt;
          &lt;form id="fieldform" action="form.php" method="post"&gt;
              &lt;fieldset id="fieldsetgroup" data-role="controlgroup"&gt;
  
                  {{each BoligPortal.AdSearch.postalcodesInSelectedCounty}}
                      &lt;input type="checkbox" name="checkbox-${zipcode}-${timestamp}" id="checkbox-${zipcode}-${timestamp}" class="zipcodecheckbox"/&gt;
                      &lt;label for="checkbox-${zipcode}-${timestamp}"&gt;${zipcode} ${city}&lt;/label&gt;
                  {{/each}}
              &lt;/fieldset&gt;
          &lt;/form&gt;
      &lt;/script&gt;
  
      &lt;div data-bind="template: 'countyListTemplate'"&gt;&lt;/div&gt; 
  
      &lt;div class="submit"&gt;
          &lt;a href="#searchCriteriasPage" class="navbutton submitPostnumre"&gt;Næste&lt;/a&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
