Update using XSODATA from XSJS file

Friends

Can some one help me with the code to form a AJAX "PUT" request to the XSODATA service to update the records in the Table.

I know this is possible, because, I am able to update the records in the DB using POSTMAN.

I have tried different AJAX calls. But none worked.

Would be thankful, if someone can help me with the code to get this working

Regards
