父组件添加catch事件，导致子组件tap事件无法被触发，如何解决？
<wxs src="./touch.wxs" module="touch" />
<view catch:touchstart="{{touch.touchstart}}"
catch:touchmove="{{touch.touchmove}}"
catch:touchend="{{touch.touchend}}">
<view>
<view bind:tap="handleTap">删除</view>
</view>
<view>
<view bind:tap="handleTap">删除</view>
</view>
</view>
