body: <p>I have a requirement in my project.
  I am having titles loaded in a scope variable from http call :</p>
  <pre><code> $scope.titleObject = [{
       &quot;title&quot;: &quot;Title1&quot;,
       &quot;underlinekey&quot;: &quot;t&quot; }, {
       &quot;title&quot;: &quot;Sub-Heading&quot;,
       &quot;underlinekey&quot;: &quot;u&quot; }, {
       &quot;title&quot;: &quot;Heading text&quot;,
       &quot;underlinekey&quot;: &quot;a&quot; }, {
       &quot;title&quot;: &quot;Some Title&quot;,
       &quot;underlinekey&quot;: &quot;o&quot; }, {
       &quot;title&quot;: &quot;More Title&quot;,
