title: Angular JS filter not equals
body: <p>Seems like a very basic question but I can't get the syntax right..</p>
  
  <pre><code>&lt;li class="list-group-item" ng-repeat="question in newSection.Questions | filter:Id != '-1'; " ng-mouseenter="hover = true" ng-mouseleave="hover = false"&gt;
      &lt;div href="#" editable-text="question.Text"&gt;{{question.Text}}&lt;/div&gt;
  &lt;/li&gt;
  </code></pre>
  
  <p>All I want is to show all the questions where id is NOT -1.
  What am I doing wrong. Thanks!</p>
