    var sceneEl = document.querySelector('a-scene');
    var keyboardEl= sceneEl.components['super-keyboard'];
    keyboardEl.addEventListener('superkeyboardchange', function(e) {console.log(e)});

console return 'undefined' always...
error is also emitted:
Uncaught TypeError: Cannot read property 'key' of null at line below

    setTimeout(function () {
      self.updateKeyColorPlane(self.keyHover.key, self.keyHoverColor);
    }, 100);

is the super-keyboard component actually attached to the scene? it should be attached to an entity. Maybe that's the reason it doesn't work.
