navCtrl.push and menu

Hallo

I have a little Problem with navCtrl.push and the menu, which I set in the navbar.

app.html:

<ion-menu side="right" [content]="content">
  <ion-header>
    <ion-toolbar>
      <ion-title>
        Side Menu
      </ion-title>
    </ion-toolbar>
  </ion-header>
  <ion-content padding>
    <ion-list>
      <ion-item (click)="toAppointment()">Termine</ion-item>
      <ion-item (click)="toApproval()">Genehmigungen</ion-item>
    </ion-list>


  </ion-content>


</ion-menu>


<ion-nav [root]="rootPage" #content></ion-nav>

and in the pages.html:

<ion-header>

  <ion-navbar class="header" style="color:#488aff">
    <h1>Terminvereinbarung</h1>
    <ion-buttons start>
      <button ion-button icon-only menuToggle>
        <ion-icon name="menu"></ion-icon>
      </button>
    </ion-buttons>


  </ion-navbar>


as long as I call a navCrtl.setRoot(somePage) i have in the up right the menu button to toggle the side menu. But then there is not the Back-Arrow from Push…

And when i use navCrtl.push(somePage), the menu button isn’t shown.

Is there a way to use push to keep the back-arrow, and show the button for the side menu?

thanks in advance

C-f persistent.
