How update side menu?

Ionic Framework ionic-v3
1

Hi, I have a side menu in app.component and I want to updatethis from some component like this :
app.component.html :

<ion-menu  side="right" [content]="content" >

  <ion-content >
    <ion-list>
      <button ion-item *ngFor="let p of pages" (tap)="openPage(p)">
        {{p.title}}
      </button>
    </ion-list>
  </ion-content>

</ion-menu>

<ion-nav  (onGetMember)="refreshMember(member)" [root]="rootPage" #content swipeBackEnabled="false"></ion-nav>

And I handle “onGetMember” in app.component.ts.

other.component :


export class OtherPage {
  @Output() onGetMember: EventEmitter<any> = new EventEmitter<any>();



  constructor(

  ) {

 

  login(){
    this.onGetMember.emit(data); 

    });

  }


}

But, refreshMember function not called on time .
