HarmonyOS 子组件中点击事件交给父组件处理，在父组件种修改数据后子组件不刷新

@Observed  
class GroupResponse {  
  name: string = ''  
  constructor(name: string) {  
    this.name = name  
  }  
}  
@Entry  
@Component  
struct Test15 {  
  @State data: GroupResponse = new GroupResponse("test1")  
  build() {  
    Column() {  
      Child(  
        {  
          item: this.data,  
          onItemClick: (item: GroupResponse) => {  
             item.name='test2'  
            console.log(JSON.stringify(item))  
          }  
        }  
      )  
    }  
  }  
}  
@Component  
struct Child {  
  @ObjectLink item: GroupResponse  
  onItemClick = (item: GroupResponse): void => {  
  }  
  build() {  
    Text(this.item.name)  
      .fontSize(16)  
      .onClick(() => {  
        this.onItemClick(this.item)  
      })  
  }  
}
