title: Trying to use Mustasche in Tinymce preview
body: <p>As the title suggests I am trying to get Mustasche templates to work in the Tinymce preview but it does not work.</p>
  
  <p>In Tinymce Plugins/Preview/plugin.js</p>
  
  <pre><code>previewHtml = (
                      '&lt;!DOCTYPE html&gt;' +
                      '&lt;html&gt;' +
                      '&lt;head&gt;' +
                      '&lt;script type="text/javascript" src="~/Scripts/mustache.js"&gt;&lt;/script&gt;' +
                          headHtml +
                      '&lt;/head&gt;' +
                      '&lt;body id="' + bodyId + '" class="mce-content-body ' + bodyClass + '"' + dirAttr + '&gt;' +
                          editor.getContent() +
                      '&lt;/body&gt;' +
                      '&lt;/html&gt;'
                  );
  </code></pre>
  
  <p>Stuff to preview:</p>
  
  <pre><code>var obj1 = { user: "John", age: 22, country: "United States" };
  
  {{obj1.user}}
  </code></pre>
