ember-cli-jstree actionreceiver为null

Question

我的环境版本如下： 版本：1.13.1 节点：0.12.4 npm：2.12.1 安装ember-cli-jstree时，我以这种方式使用组件：

//hbs file
{{ember-jstree
  actionReceiver=jstreeActionReceiver
  data=data
  eventDidBecomeReady="handleTreeDidBecomeReady"
  }}
and

//controller
App.MyController = Ember.Controller.extend({
jstreeActionReceiver: null,
data:[],
action:{
handleTreeDidBecomeReady:function(){
      console.log(this.get('jstreeActionReceiver'));       
      }
}
})

jstreeActionReceiver为空，那么我犯了什么错误？
