Event Listeners In Ar.js

I am developing a project which involves ar.js that is displaying 3d objects and text to teach children the alphabet on both mobile devices and laptops. I was trying to add an even

Solution 1:

I think the main issue is something with a-frame version 1.0.X. For some reason the addEventListerner('click') won't work if I use that.

Below is my code, you click your model and it should increase the scale. Note: there is issue about the click event not at the expected spot.

        AFRAME.registerComponent('button', {
            init: function() {

                const gltf = document.querySelector('#animatedApple');
                var x = gltf.getAttribute('scale').x;
                var y = gltf.getAttribute('scale').y;
                var z = gltf.getAttribute('scale').z;

                // every click, we make our model grow in size :)
                gltf.addEventListener('click', function(ev, target){
                    console.log(gltf.getAttribute('scale'));
                    gltf.setAttribute('scale', x + " " + y + " "+ z);
                    x += 0.1;
                    y += 0.1;
                    z += 0.1;
                });
            }
        });
