Aframe elements won't simply react to touch / mouse events. You need a ray based cursor.

A good way to simulate the mouse is with the cursors attribute:

<a-scene cursor="rayOrigin: mouse>

It should also work with touch events on mobile devices.

Check it out here.

Otherwise use the a-frame cursor.

<a-cursor></a-cursor>
