title: how to add angular tags to html attribute in razor
body: <p>rather than do this</p>
  
  <pre><code>&lt;input type="checkbox" name="AltSchedule" ng-show="someVar" /&gt;
  </code></pre>
  
  <p>i want to be able to do this</p>
  
  <pre><code>@Html.CheckBoxFor(model =&gt; model.AltSchedule, new  {ng-show="someVar" })
  </code></pre>
  
  <p>but i can't seem to find an answer on who to accomplish using the html helpers with angular tags.  Is there way to add angular tags to the html attributes parameter for an html helper?</p>
