离子载玻片盒在离子框架中不起作用

Question

我的观点如下：

<ion-view title="Slides" ng-controller='IntroCtrl'>
  <ion-content ng-controller='IntroCtrl'>
    <h3> Slides here </h3>
    <!-- <ion-nav-buttons side="left">
              <button class="button button-positive button-clear no-animation"
                      ng-click="previous()" ng-if="data.slideIndex > 0">
                Previous Slide
              </button>
            </ion-nav-buttons>
            <ion-nav-buttons side="right"> 
              <button class="button button-positive button-clear no-animation"
                      ng-click="next()" ng-if="data.slideIndex < data.numViewableSlides - 1">
                Next
              </button>
            </ion-nav-buttons>-->
    <ion-slide-box on-slide-changed="slideChanged(index)">

      <ion-slide ng-repeat="slide in data.slides">
        <div ng-include src="slide.template"></div>
      </ion-slide>


    </ion-slide-box>
  </ion-content>
</ion-view>

控制器

.controller('IntroCtrl', function($scope, $state, $ionicSlideBoxDelegate, $ionicSideMenuDelegate) {
  $scope.$on('$ionicView.enter', function() {
    $ionicSideMenuDelegate.canDragContent(false);
  });
  $scope.$on('$ionicView.leave', function() {
    $ionicSideMenuDelegate.canDragContent(true);
  });
  $scope.data = {
    numViewableSlides: 0,
    slideIndex: 0,

    slides: [{
        'template': 'templates/mylongform.html'
      },

      {
        'template': 'templates/facts.html'
      },

      {
        'template': 'templates/facts2.html'

      }
    ]
  };

  var countSlides = function() {
    $scope.data.numViewableSlides = 0;

    for (var i = 0; i < $scope.data.slides.length; i++) {
      $scope.data.numViewableSlides++;
    }

    console.log($scope.data.numViewableSlides + " viewable slides");

  }

  countSlides();


  $scope.next = function() {
    $ionicSlideBoxDelegate.next();
    console.log("called next")
  };
  $scope.previous = function() {
    $ionicSlideBoxDelegate.previous();
    console.log("called previous")
  };



  // Called each time the slide changes
  $scope.slideChanged = function(index) {

    $scope.data.slideIndex = index;
  };

})

我使用过slideMenu Delegate，因为没有它，每次我尝试滑动时都会刷一下侧面菜单。

但即使是现在，滑块也不起作用。 这里看错了什么？
