Zendesk - Requester isn't getting Change properly

I am working on Zedesk server side App, I want to change Ticket Requester pragmatically.
I am trying following way of doing it.

zendeskClient.set({'ticket.requester': {email:data[0].email, name:data[0].name}});

It is updating email instead of name. On the requester field, there should be a requester Name, but currently it is showing email instead of name.
