Hi,
I am working with Datatables Editor in trial and it is nice piece of sofware 
sure will buy it
I am sending all (Datatables + Editor) POST on one ajax url...
I think will nice if also Datatables will have in future post parameter ACTION as has Editor
https://editor.datatables.net/manual/server
By this will cover all situation of CRUD actions of datatables and will better handle in code the post request from both Datatables.
