您的onScrollEnd事件绑定到视图的顶部元素; scrollEnd将当视图的HTML元素接收到onScrollEnd事件时调用。

Your onScrollEnd event is bound to the view's top element; scrollEnd will be called when the view's HTML element received an onScrollEnd event.

但是您触发了View对象上的onScrollend事件而不是元素。

But you are triggering an onScrollend event on your View object, not the element.

所以你可能想说 $（self.el）.trigger（'onScrollEnd'）; ，或者直接调用函数： self.scrollEnd（）。

So you probably want to say $(self.el).trigger('onScrollEnd'); instead, or perhaps call the function directly: self.scrollEnd().
