Ordering children with drag & drop, how to trigger "dash component has changed" from JS

Hi chris8,

I don’t have much experience with Dash yet but I find the example above very interesting. I am trying it out right now. When I import EventListener and compile it, I get an Error message:

from dash_extensions import EventListener
ImportError: cannot import name ‘EventListener’ from ‘dash_extensions’.

I have installed (with pip) Dash Extensions version 0.1.10 and Dash version 2.8.1.

Do you know why I can’t import EventListener?
Thanks.
