Button attached above the keyboard

Ionic Framework ionic-v3
1

I’m trying to attach a simple button (“send”) above the keyboard.

I have tried to put it in a footer, with no success :

<ion-footer id="footer">
      <ion-toolbar class="keyBoardButton" no-border>
        <button ion-button full (click)="send()" >Send</button>
      </ion-toolbar>
</ion-footer>

I’m actually using a custom directive that I posted here but it put the mess with other directives.

What’s the best way for achieving this ?

Thanks
