微信小程序事件传参与数据同步

Question

index.js:
Page({
  data: {
    count: 0
    },
    CountChange(){
      this.setData({
        count:this.data.count+1
      })
          
        }
  })
index.wxml:
<button type="primary" bind:tap="CountChange">button</button>

Console中：Component "pages/index/index" does not have a method "CountChange" to handle event "tap".
AppData中没有count
