Button in slides

Ionic Framework ionic-v3
1

I have a basic slider

<ion-slides>
  <ion-slide>
    <h1>Slide 1</h1>
    <button (click)="doAction()">Click me</button>
  </ion-slide>
  <ion-slide>
    <h1>Slide 2</h1>
  </ion-slide>
  <ion-slide>
    <h1>Slide 3</h1>
  </ion-slide>
</ion-slides>

And in my ts file

doAction() {
    console.log("clicked");
}

Clicking the button does nothing. If I place the button anywhere outside the slider it works fine. Is the slider capturing the click event somehow?
