title: ionic $ionicSlideBoxDelegate slidesCount not correct after update
body: <p>I'm writing a simple ionic app. My controller is quite simple so far..</p>
  
  <pre><code>.controller('CardsCtrl', function($scope, dataFactory, $ionicSlideBoxDelegate, $stateParams) {
  
      var parentID = $stateParams.parentID;
      var keyIDNumber = $stateParams.keyID;
  
      $scope.card = [];
  
  
      var httpcall = dataFactory.getPosts()
          .success(function (posts) {
  
              $scope.card = dataFactory.getChildPosts(parentID, posts, keyIDNumber);
  
              $ionicSlideBoxDelegate.update();
              console.log($ionicSlideBoxDelegate.slidesCount());
           });
  
      //more stuff....
  </code></pre>
  
  <p>})</p>
  
  <p>My template has an ng-repeat so I .update() on success of the data and so all my slides are there as I would expect. However, $ionicSlideBoxDelegate.slidesCount() is still returning 0 after the .update() - even though I have got five slides at the moment. </p>
  
  <p>Even though the .update() doesn't seem to require it I've tried adding a $getByHandle but to no avail! Any ideas how I can get the slide count?</p>
