Editing is described in great detail in the Inline Editing page - so make sure you read that first.

This page is just a chart that describes the editing flow with the most important steps:

• starting the edit - via the API or by user interaction (which triggers the API call)
• checking if the cell is editable - async checks are also supported
• retrieving the value to edit
• stopping the edit - via API or by user interaction
  • an edit can be cancelled - value discarded
  • an edit can be rejected - value rejected with error
  • an edit can be accepted - value accepted and passed to the persit layer
• persisting the edit
  • defaulting to updating data to the data source
  • a custom persist function can be provided via persistEdit
• notifying the user of the result of the edit
  • onEditCancelled
  • onEditRejected
  • onEditAccepted - after accepting the edit, either the persist success or error is called
    • onEditPersistSuccess
    • onEditPersistError
