HarmonyOS 数据更新不了问题

当去修改了数组中的某个Model的 localSelected 状态时，子组件的页面不刷新

父组件

@State goalsLabels: Array<CsUserLabelBean> = new Array()
// 创建子组件
CsCoLabelTabContents({ labels: this.goalsLabels })

子组件代码：

@Component
export struct CsLabelItem {
  @ObjectLink item: CsUserLabelBean

  build() {
    Text(this.item.title)
      .margin({
        left: ds2vp(4),
        right: ds2vp(4),
        top: ds2vp(5.5),
        bottom: ds2vp(5.5)
      })
      .textAlign(TextAlign.Center)
      .fontSize(ds2vp(13.33))
      .fontColor(this.item.localSelected ? '#FFFFFF' : '#965E31')
      .backgroundColor(this.item.localSelected ? '#C78652' : '#FBF1E2')
      .borderRadius(ds2vp(12))
      .width(ds2vp(90))
      .height(ds2vp(24))
      .padding({ left: ds2vp(4), right: ds2vp(4) })
      .maxLines(1)
      .textOverflow({ overflow: TextOverflow.Ellipsis })
      .border({
        width: ds2vp(1),
        color: this.item.localSelected ? '#FBF1E2' : '#E9C47C',
        style: BorderStyle.Solid
      })
  }
}

@Component
export struct CsCoLabelTabContents {
  @Prop labels: Array<CsUserLabelBean>

  build() {
    Column() {
      Grid() {
        ForEach(this.labels, (item: CsUserLabelBean, index: number) => {
          GridItem() {
            CsLabelItem({ item: item })
          }
        })

      .scrollBar(BarState.Off)
      .columnsTemplate('1fr 1fr 1fr 1fr 1fr 1fr')
      .width(ds2vp(611))
