FabricJS Catch click on object inside group

I downloaded fabricjs from asturur repo. build fabric.js file

node build.js modules=ALL exclude=json,gestures

and it works!

Then you can use events on objects in the groups.

canvas._objects[0]._objects[0].on('mousedown', function(e){ this.stroke = 'black'});

In my app i decided to search for events from mousedown callback

group.on('mousedown', function(e){
    var innerTarget  = group._searchPossibleTargets(e.e);
    console.log(innerTarget);
});

group._searchPossibleTargets = function(e) {
    var pointer = this.canvas.getPointer(e, true);
    var i = objects.length,
        normalizedPointer = this.canvas._normalizePointer(this, pointer);

    while (i--) {
        if (this.canvas._checkTarget(normalizedPointer, this._objects[i])) {
            return this._objects[i];
        }
    }
    return null;
}
