get the current index of the array using the event method?

[Stan92]

Hi,
Thanks for sharing this plugin.
Using your example for binding the polyline

     for (var i = 0, latlngs = [], len = data.model.length; i < len; i++) {
              latlngs.push(new L.LatLng(data.model[i].latitude, data.model[i].longitude));
      }

Is there a way to get the index from the

.on('snakestart snake snakeend', function (ev) {
                            console.log(ev);
});

I have extra data in my model and would like to use them from the event method.

Thanks for your support
