There is no "ss-event-dragged" event in version 2

[Serob]

Hi, the documentation says "When an item has begun being dragged, it will trigger the "ss-event-dragged" on the container element", but I can not find "ss-event-dragged" event in version 2.0.
This code does nothing on drag:
$cards.on("ss-event-dragged", function(e, selected) {
console.log("Enter drag mode");
});
