在emberjs嵌套视图中未定义值

我有一个脚本把手..

<script id="ownerItem" data-template-name='ownerItem' type="text/x-handlebars">
    {{value.UserName}} &nbsp;<button {{action "remove" on="click"}}>Remove</button>
</script>  

它的观点..

ResAdmin.ownerView = Ember.View.extend({
    templateName: 'ownerItem',
    remove: function() {
      var selectedRest;
      selectedRest = ResAdmin.adminController.get('selectedRestaurant');
      alert(value.RestaurantOwnerID);
      return $.ajax({
        url: '/api/RestaurantOwner/' + value.RestaurantOwnerID,
        cache: false,
        type: 'delete',
        data: {
          RestaurantID: selectedRest.RestaurantID,
          MethodOverride: 'delete'
        },
        dataType: 'jsonp',
        success: function(data) {
          return ResAdmin.adminController.getRestaurantList();
        }
      });
    }
  });

在其他一些视图中,我正在使用此视图,如

  {{#each ResAdmin.adminController.selectedRestaurant.Owners}}
            {{view ResAdmin.ownerView valueBinding="this" content="this"}} 
        {{/each}} 

但是当我点击我的嵌套视图的删除按钮时,我收到错误(值未定义)...有人可以帮助我吗?

value是ownerView的属性,因此您需要使用this.get('value')

对其进行限定

e.g。

this.get('value').RestaurantOwnerId
