GridfieldExtension Reordering Event?

Silverstripe Version:

Question:

Hey everybody!!
In my Silverstripe 3 Project I use a Gridfield with the Orderable rows feature enabled. Is there a possibility to use an event or Callback after reordering an item in my gridfield?

First I thought I can use the onBeforeWrite Callback of the reordered dataobject but the event does not seem to be fired ob a reorder action.

You guys have any idea what I can use? I have to fire some custom action when my gridfield items are reordered! :slight_smile:

Thanks!!!
