微信小程序里 wx.showActionSheet 使用?

Question

<view bindtap="openActionsheet">打开 Actionsheet</view>
<view>data: </view>

Page({

     data: {

     },
     openActionsheet() {
          wx.showActionSheet({
               itemList: ['菜单1', '菜单2'],
               success(res) {
                    console.log(res)
                    this.setData({
                         data: res
                    })
               }
          })
     }

})

选择后报了一个setData 未定义的错
我需要在<view>data: </view>这里接收到选择的菜单, 应该如何实现?

<view bindtap="openActionsheet">打开 Actionsheet</view>
<view>data: {{ res }}</view>

Page({

     data: {
        res: "",
     },
     openActionsheet() {
          const itemList = ['菜单1', '菜单2']; 
          wx.showActionSheet({
               itemList,
               success: (res) => {
                    console.log(res)
                    this.setData({
                         res: itemList[res.tapIndex]
                    })
               }
          })
     }

})
