Hello Ronak Patel,

This issue has been fixed in the latest version of Smart UI, please update your package and try again.
In the demo here, you see that endEdit is called even when the user deletes the cell value

If you don’t want to allow users to remove the cell value, you may consider using Cells Editing Validation
You can have a look at the demo here: Angular – Cell Validation Demo

If you have any other questions, please do not hesitate to contact us again.
Best regards,
Ivan Peevski
