How to call $scope.$apply() using "controller as" syntax

Question

I am trying to limit my use of $scope in my controllers as much as possible and replace it with the Controller as syntax.

My current problem is that i'm not sure how to call $scope.$apply() in my controller without using $scope.

Edit: I am using TypeScript 1.4 in conjunction with angular

I have this function

setWordLists() {
  this.fetchInProgress = true;
  var campaignId = this.campaignFactory.currentId();
  var videoId = this.videoFactory.currentId();

  if (!campaignId || !videoId) {
    return;
  }

  this.wordsToTrackFactory.doGetWordsToTrackModel(campaignId, videoId)
  .then((response) => {
    this.fetchInProgress = false;
    this.wordList = (response) ? response.data.WordList : [];
    this.notUsedWordList = (response) ? response.data.NotUsedWords : [];
  });
}

being called from

$scope.$on("video-switch",() => {
           this.setWordLists();
});

And it's (the arrays wordList and notUsedWordList) is not being updated in my view:

<div class="wordListWellWrapper row" ng-repeat="words in wordTrack.wordList">
  <div class="col-md-5 wordListWell form-control" ng-class="(words.IsPositive)? 'posWordWell': 'negWordWell' ">
    <strong class="wordListWord">{{words.Word}}</strong>
    <div class="wordListIcon">
      <div class="whiteFaceIcon" ng-class="(words.IsPositive)? 'happyWhiteIcon': 'sadWhiteIcon' "></div>
    </div>
  </div>
  <div class="col-md-2">
    <span aria-hidden="true" class="glyphicon-remove glyphicon" ng-click="wordTrack.removeWord(words.Word)"></span>
  </div>
</div>

Along the same lines of $apply, is there another way of calling $scope.$on using Controller as?

Thanks!

Solution

To answer the question at hand here, you can use $scope() methods in a controller when using the controller-as syntax, as long as you pass $scope as a parameter to the function. However, one of the main benefits of using the controller-as syntax is not using $scope, which creates a quandary.

As was discussed in the comments, a new question will be formulated by the poster to review the specific code requiring $scope in the first place, with some recommendations for re-structuring if possible.

under 99% of all situations, you only need to call $scope.$apply() when you operate on the dom directly without angular's knowledge. Unfortunately, many people resort to $scope.$apply() as a "fix-all" when something doesn't work, but usually the better thing to do is correct the code so that angular is aware of what is happening.

your code doesn't really show where the $scope.$on() function is at in the controller, so perhaps we take a bit closer look at the controller code?

If you code isn't working you should post it as another question, as you have already asked about something else here. People will be confused otherwise :)
