Icon button in card header don't float right and not vertical centered

[Nexi]

You can wrap it into and it works like this:

Is that what you want? Here the code:

<ion-card-header>
      <ion-item>
        Indikationen
        <button ion-button icon-only item-right clear>
        <ion-icon name="md-create"></ion-icon>
      </button>
      </ion-item>
</ion-card-header>

The ion-icons are a font, so you can resize them by changing the font-size of the ion-icon tag with css
