How can I display data from nested JSON in the context of the ng-click (Angular, JSON)

Question

I'm trying to figure out how I can display nested json data that pertains to the data from the previous ng-click.

Any insight would be greatly appreciated, thanks!

HTML

<ul class="list-unstyled">
  <li ng-repeat="content in contentSets" ng-click="setContent(content)">
    <a href="#">{{content.name}}</a>
  </li>
</ul>

<h1>{{useContent.contentTitle}}</h1>

<ul class="list-unstyled">
  <li ng-repeat="headline in useContent.headlines">
    {{headline.title}}
  </li>
</ul>

JS

 function AppController($scope, $http) {

   $http.get('content.json').success(function(data) {
     $scope.contentSets = data.contentData;

     $scope.news = [];
     $scope.headlines = [];

     angular.forEach(data.contentData, function(demoContent, index){

      angular.forEach(demoContent.news, function(newsGroup, index){
       $scope.news.push(newsGroup);

       angular.forEach(newsGroup.headlines, function(headline, index){
        $scope.headlines.push(headline);
       });
     });
    });

  });

  $scope.setContent = function(content) {
    $scope.useContent = content;
  }
}

You can do it directly in view:

<ul class="list-unstyled" ng-repeat="news in useContent.news">
  <li ng-repeat="headline in news.headlines">
    {{headline.title}}
  </li>
</ul>
