地图上展示marker，marker上展示气泡callout，因展示的内容太多，使用的自定义callout，参照文档里提供的demo，实现了，我想要的效果，但是点击事件没反应，请问如何处理？

 <view>
    <map class="home-map" scale="{{currentScale}}" longitude="{{currentLongitude}}" latitude="{{currentLatitude}}" markers="{{markers}}" bindtap="bindtapmap" bindmarkertap="bindmarkertap" show-location="true">
      <cover-view slot="callout">
        <block wx:for="{{customCalloutMarkerIds}}" wx:key="*this">
          <cover-view class="customCallout" marker-id="{{item}}" >
            <cover-view class="content" > 
              <cover-view bindtap="trackPlayBack">车牌号{{currentMarker.id}}</cover-view>
              <cover-view>车牌号{{currentMarker.name}}</cover-view>
              <cover-view>车牌号{{currentMarker.latitude}}</cover-view>
              <cover-view>车牌号{{currentMarker.longitude}}</cover-view>
              <cover-view>车牌号{{currentVehicle}}</cover-view>
            </cover-view>
          </cover-view>
        </block>
      </cover-view>
    </map>
  </view>

trackPlayBack(){
  console.log(111111)
  wx.navigateTo({
    url: '/pages/trackPlayBack/trackPlayBack',
  })
}
