WXML bindtap 只能调用一次

<view class="weui-uploader__input-box">
   <view class="weui-uploader__input" bindtap="chooseVideo"></view>
</view>

    async chooseVideo(e) {
        console.log("chooseVideo 调用了1次")
        this.setData({
            chooseVideoStatus: "loading"
        })
        await wx.chooseMedia({
            count: 1,
            mediaType: ['video'],
            sourceType: ['album', 'camera'],
            maxDuration: 30,
            success: res => {
                // console.log(res.tempFiles[0].tempFilePath)
                this.chooseVideo = res.tempFiles[0].tempFilePath;
                this.setData({
                    chooseCover: res.tempFiles[0].thumbTempFilePath,
                }, () => {
                    const id = setTimeout(() => {
                        this.setData({
                            chooseVideoStatus: "choose"
                        });
                        clearTimeout(id);
                    }, 2000)
                })
            },
            fail: err => {
                console.log('choose Media fail.')
                this.setData({
                    chooseVideoStatus: null
                })
            }
        })
    },

经过测试，将 chooseVideo 改成其他名称后，运行正常。

怀疑是 因为自定义函数 和 wx.chooseVideo 冲突。
