scrollView的父节点监听touch事件

Creator 2.x
#1

在canvas上放了一个scrollView，canvas节点监听了touch_start和touch_end，点击scrollview区域无法触发，请问如何解决
version：2.0.4

#2

//This is for Scrollview as children of a Button
_stopPropagationIfTargetIsMe (event) {
if (event.eventPhase === cc.Event.AT_TARGET && event.target === this.node) {
event.stopPropagation();
}
},

#3

on的第四个参数设为true

#4

可以监听到了，谢谢
