HarmonyOS AttributeModifier封装bindPop问题

//这是AttributeModifier
export class GmPopTipsAttribute implements AttributeModifier<CommonMethod<RowAttribute>> {
  showPop: boolean = false
  text?: string

  constructor() {
  }

  applyNormalAttribute(instance: CommonMethod<RowAttribute>): void {
    instance.bindPopup(this.showPop, {
      builder: () => {
        wrapBuilder(GmPopTipsBuilder).builder(this.text)
      },
      placementOnTop: true,
      showInSubWindow: false,
      arrowHeight: 5,
      arrowWidth: 10,
      enableArrow: true, //显示箭头
      arrowPointPosition: ArrowPointPosition.CENTER,
      radius: 3, //圆角
      onStateChange: (e) => {
        if (!e.isVisible) {
          this.showPop = false
        }
      }
    })
  }
}

@Builder
export function GmPopTipsBuilder(value: string) {
  GmPopTipsView({
    value: value
  })
}

@Component
export struct GmPopTipsView {
  value?: string

  build() {
    Column() {
      Text(this.value)
        .padding({
          left: 10,
          right: 10,
          top: 5,
          bottom: 5
        })
        .fontSize(14)
        .fontColor("#2a3050")
    }
  }
}

//初始化准备
@State popAttribute: GmPopTipsAttribute = new GmPopTipsAttribute()
//随便找个地方执行
this.popAttribute.text = `测试`
//随便找个组件调用
.attributeModifier(this.popAttribute)
//报错-Error message:Method not implemented

需要如何修改？
