angularjs – 如何调用$scope $apply()使用“controller as”语

我当前的问题是，我不知道如何调用$ scope。$ apply()在我的控制器中，而不使用$ scope。

编辑：我正在使用TypeScript 1.4与角度

我有这个功能

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 : [];
  });
}

被叫来

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

它是(数组wordList而notUsedWordList)
在我看来没有更新：

<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>

按照同样的条件申请，是否有另一种方式调用$ scope。$ on使用Controller作为？

谢谢！
