HarmonyOS 二维数据数据传递最里面的对象，改变最里面的值页面不更新

示例参考如下：

@Observed
class ZLKShopCartModel {
  productId: string = ''
  productName: string = ''

  constructor(productId: string, productName: string) {
    this.productId = productId;
    this.productName = productName;
  }
}

@Observed
class ZLKShopCartListModel {
  showId: number = 0
  showList: Array<ZLKShopCartModel> = []

  constructor(showId: number, showList: Array<ZLKShopCartModel>) {
    this.showId = showId;

    this.showList = showList;
  }
}


@Component
struct ZLKShopCartItemView {
  @ObjectLink model: ZLKShopCartModel;

  build() {
    Column() {
      Text(this.model.productName)
      Button('修改为11111')
        .onClick(() => {
          this.model.productName = "11111"
        })
    }
  }
}

@Entry
@Component
struct ZLKShopCart {
  @State ZLKTShowList: Array<ZLKShopCartListModel> = [];

  onPageShow(): void {
    this.ZLKTShowList =
      [new ZLKShopCartListModel(1, [new ZLKShopCartModel("02233", 'ArkUI'), new ZLKShopCartModel("02233", 'ArkTS')])]
  }

  build() {
    Column() {
      List() {
        ForEach(this.ZLKTShowList, (listModel: ZLKShopCartListModel, index: number) => {
          ListItemGroup() {
            ForEach(listModel.showList, (model: ZLKShopCartModel, row: number) => {
              ZLKShopCartItemView({
                model: model
              })
            })
          }
        })
      }
    }
  }
}
