Button and checkbox in Slide element

Basically I'm trying to place a checkbox and a button in the ion-slide

<ion-slides pager>
<ion-slide style="background-image:url('img/end.png'); background-size: 100%;">
   <br>
<ion-checkbox>Do not show this again</ion-checkbox>
 <button secondary (click)="homePage()">Done</button>
 </ion-slide>

</ion-slides>

However, the button and the checkbox cannot be clicked. Both button and checkbox does work when it is placed in a regular page. Is this a bug?
