The Create method has a potential problem in that it assumes that it succeeds immediately. It does not handle the success event for the operation. Additionally, there is a further issue in that add operations have a complete event because the success event may fire before the record has been successfully written to the disk, and, if the transaction fails, the complete event is not raised. You can convert the Create method so that it uses a promise and resumes processing when the success event is raised. Then, update the insert portion of the component to reload once this has been completed.

The deletion resets the state even if the user wasn't editing the record that was deleted. So, enhance the delete code to only reset the state if the record being edited is the same as the one that was deleted.
