Ionic 2 (click) is triggered twice

I am developing an app with Ionic 2, but I found the problem with the click event when trying the application on a device, in this case it is an iphone.

This is the code I use to generate an alert, it's simple but it's triggered twice.

home.html

<div padding>
    <button ion-button full (click)="TestAlert()">Alert</button>
</div>

home.ts

TestAlert(){

     console.log('Hola');
     alert('Hola');
  }

If someone knows if it is a problem of framework configuration or has the same problem and solved it, it would be very helpful.

I also share the example of what I am doing in this repository
