[SOLVED] object clicked event capture via api?

in your main.js how can capture if an object are clicked?, thx.

I want to combine it with Magnific Popup libraries (or shadowbox or lightbox or lightcase, etc).

var m_app  = require("app");
var m_data = require("data");
var m_anim = require("animation");
var m_scenes = require("scenes");

function init_cb(canvas_elem, success) {
……
canvas_elem.addEventListener("mousedown", main_canvas_click, false);
}

function main_canvas_click(e) {
    if (e.preventDefault)
        e.preventDefault();

    var x = e.clientX;
    var y = e.clientY;

    var obj = m_scenes.pick_object(x, y);

    if (obj) {
        var n = obj.name;
        if (n == 'pelota_05') {
            $.magnificPopup.open({
                items: {
                    type:'inline',
                    src: '<div class="white-popup" data-effect="mfp-zoom-in">Punto de explicacion 01</div>',
                }
            });
        }
    }
}
