HarmonyOS 鸿蒙Next Refresh组件下拉刷新UI无反应，debug过list是有数据的，帮忙看看什么问题

改成用@State装饰器去定义数据，具体改动如下：

@Entry
@Component
struct TestPage {
  [@State](/user/State) isRefreshing: boolean = false
  [@State](/user/State) commentsList :CommentList[] = []

  build() {
    Refresh({ refreshing: this.isRefreshing, builder: this.customRefreshComponent()}) {
      List() {
        ForEach(this.commentsList, (item: CommentList, index:number) => {
          ListItem() {
            Row(){
              Image($r('app.media.background'))
                .alt($r('app.media.foreground'))
                .height(20).width(20)
                .margin(8)
              Text() {
                Span(item.name + '：')
                  .fontColor(Color.Black)
                  .fontSize('14fp')
                Span(item.content)
                  .fontColor(Color.Brown)
                  .fontSize('14fp')
              }
              .margin({top:10,bottom:10,right:12})

            }.margin({top:5,bottom:5,left:20,right:20})
            .borderRadius(4)
            .backgroundColor(Color.Pink)
          }
        })
      }
      .scrollBar(BarState.Off)
      .width('100%')
      .height('100%')
      .margin({top:50})
    }
    .onRefreshing(() => {
      this.commentsList = [...this.commentsList,new CommentList('111','党的二十届三中全会通过的222')]

      //this.commentsList.push(new CommentList('111','党的二十届三中全会通过的2222'))
      this.isRefreshing = false
    })
  }

  aboutToAppear(): void {
    this.commentsList.push(new CommentList('111','党的二十届三中全会通过的'))
    this.commentsList.push(new CommentList('222','党的二十届三中全会通过的中共中央关于进一步全面深化改革'))
    this.commentsList.push(new CommentList('333','习近平总书记在关于《决定》的说明中强调，决定稿起草过程中把握的重点之一，就是“强化系统集成，加强对改革整体谋划、系统布局，使各方面改革相互配合、协同高效”。'))
    this.commentsList.push(new CommentList('444','创新是引领发展的第一动力。为了促进创新活动持续开展，需要建立一套稳定高效的制度环境。此次《决定》专门开辟一章，要求“构建支持全面创新体制机制”，“健全新型举国体制”，“提升国家创新体系整体效能”。'))
  }

  customRefreshComponent()
