ember.js中的事件处理程序

Question

I am trying to trigger an event from an Ember.js controller. 我正在尝试从Ember.js控制器触发事件。 I throws an error saying "ember.min.js:3 Uncaught Error: Nothing handled the action 'clicked'. If you did handle the action, this error can be caused by returning true from an action handler in a controller, causing the action to bubble.". 我抛出一个错误，指出“ ember.min.js：3未捕获的错误：什么都没有处理动作'单击'。如果您确实处理了该动作，则可能是由于从控制器中的动作处理程序返回true导致此错误而导致的泡沫。” Also I am not clear on how the event system works on itself for the targeted action. 我也不清楚事件系统如何针对目标动作自行工作。 C an someone help me with this. 有人可以帮我弄这个吗。 Here is my code: 这是我的代码：

You don't have an action with the name 'clicked', and you tell your code to look for an action 'clicked' on clicking the button. 您没有名称为“ clicked”的操作，并且告诉您的代码在单击按钮时查找“ clicked”的操作。 Change 更改

{{action "clicked"}}

into 进入

{{action "clickMe"}}

or change the 或更改

clickMe(){

action into 行动成

clicked(){

and everything should be fine. 一切都会好起来的。
