This doesn’t work.

<ion-header>
  <ion-navbar>
    <ion-title>title</ion-title>
    <ion-buttons right>
      <button menuToggle>
        <ion-icon name="menu"></ion-icon>
      </button>
    </ion-buttons>
  </ion-navbar>
</ion-header>

You can set end in ion-buttons.

<ion-buttons end>
  <ion-icon name="search"></ion-icon>
</ion-buttons>
