Current behavior
Currently there is no callbacks for when the editor is closed.
Expected behavior
There should be callbacks, which can be used submit altered data via an ajax, or cancel which would be used to revert cell data back to the original.

• PrimeReact version:
  3.1.3

• Browser: [all ]

• Language: [all]

I have a working fork'd example which I will make a PR for soon.

Currently the editor is only closed when enter or tab is pressed, or via blur.
Escape should also close and call cancel.
Via blur should not be considered a cancel, but it might be good to have this be configurable.

In my DataTable I have double-click goto another page, the detail for the row. In that case neither onSubmit or onCancel is called, I think this might be the right course of action.
