title: Factory only retrieves $http on load of app, how to force it to retrieve feed every time controller calls it?
body: <p>I have a very simple factory:</p>
  
  <pre><code>.factory('NewsHandler', function ($http) {
  
    return $http.get('http://server.com/feed/news.json');
  
  });
  </code></pre>
  
  <p>And in my partials I'm calling this factory like so:</p>
  
  <pre><code>  $scope.news;
    NewsHandler.success(function(data) {
      $scope.news = data;
    });
  </code></pre>
  
  <p>It seems the factory is only called once the app loads. I'm trying to get it to load every time I go from one partial to another and back. How can I make sure that happens?</p>
