HarmonyOS @Monitor没有响应

将TextInput和data.text双向数据绑定后可以实现想要的效果，参考demo如下：

@Entry
@ComponentV2
struct Index {
  data: Data = new Data();

  build() {
    Column() {
      Button("change name")
        .onClick(() => {
          this.data.name = "Jack"; // 能够触发onNameChange方法
        })
      Text(`name:${this.data.name}`)
      TextInput({ text: $$this.data.text })
      Text(this.data.text)
    }
  }
}

@ObservedV2
class Data {
  @Trace name: string = "Tom";
  @Trace text: string = '0'

  // name被@Trace装饰，能够监听变化
  @Monitor("name")
  onNameChange(monitor: IMonitor) {
    console.log(`name change from ${monitor.value()?.before} to ${monitor.value()?.now}`);
  }

  @Monitor("text")
  onTextChange(monitor: IMonitor) {
    console.log(`Text change from ${monitor.value()?.before} to ${monitor.value()?.now}`);
  }
}
