Ang5材质对话框es5与es6中的组件

Question

I want to load a component inside a dialog, I did it in "old" style with $scope and dependency injection and it's working.

    angular
  .module("MyApp", ["ngMaterial"])
  .controller('AppCtrl', function($scope, $mdDialog, $rootElement) {
    $scope.inputText = "Hello from the Input"

    $scope.openDialog = function() {
      $mdDialog.show({
        template: '<test text="inputText"></test>',
        clickOutsideToClose: true,
        parent: $rootElement,
        scope: $scope,
        preserveScope: true,
      });
    };
  })
  .component('test', {
    template: '<span>{{ $ctrl.text || "Default Text" }}</span>',
    bindings: {
      text: '<'
    }
  });

"old" style codepen

However I rewrite it to ES6 style, then the binding I'm trying to pass text is not longer available. any idea what am I missing?

class AppCtrl{ 
  constructor($mdDialog) {
    this.$mdDialog = $mdDialog;
    this.inputText = "Hello from the Input";
    this.openDialog = this.openDialog.bind(this);
  }

  openDialog() {
    this.$mdDialog.show({
      template: '<test text="this.inputText"></test>',
      clickOutsideToClose: true,
      preserveScope: true,
    });
  }; 
}

angular
  .module("MyApp", ["ngMaterial"])
  .component('test', {
    template: '<span>{{ $ctrl.text || "Default Text" }}</span>',
    bindings: {
      text: '<'
    }
  })
  .controller('AppCtrl',AppCtrl);

ES6 style codepen

Answer 1

I was playing with the implementation, seems that ES6 is working now

 class AppCtrl{ 
  constructor($mdDialog) {
    this.$mdDialog = $mdDialog;
    this.inputText = "Hello from the Input";
  }

  openDialog() {
    this.$mdDialog.show({
      template: '<test text="vm.inputText"></test>',
      clickOutsideToClose: true,
      controller:()=>this,
      controllerAs: 'vm'
    });
  }; 
};

angular
  .module("MyApp", ["ngMaterial"])
  .component('test', {
    template: '<span>{{ $ctrl.text  }}</span>',
    bindings: {
      text: '<'
    }
  })
  .controller('AppCtrl',AppCtrl)
