请问自定义组件内的点击事件时机要怎样传给调用自定义组件的页面里来？

//父页面WeChatPage.ets  
import { wechatLoginBtn } from './wechatLoginBtn';  
import { router } from '@kit.ArkUI';  
  
@Entry  
@Component  
struct WechatPage {  
  @State message: string = '调用页';  
  jump = (count: number): void => {  
    router.pushUrl({ url: '**具体路由' })  
  }  
  
  build() {  
    Row() {  
      Column() {  
        Text(this.message)  
          .fontSize(25)  
          .fontWeight(FontWeight.Bold)  
  
        wechatLoginBtn({  
          clickEvent: (num: number) => {  
            this.jump(num);  
          }  
        })  
  
      }  
      .width('100%')  
    }  
    .height('100%')  
  }  
}
