Ionic contenteditable keyup, keydown events not working correctly

#1

I have the following div:

 <div
         contenteditable="true"
        (input)="onInput($event)"
        (keyup)="onKeyUp($event)"
>
</div>

The input event doesn’t give me any information

The onKeyUp event always returns event.keyCode === 229, same for event.which. Is there anyway I can get the correct keyCode pressed on the android device?
