How to transfer new title of a book to device

Hi!

I have a book that I'm reading already in my Kindle device. In Calibre I have modified the title and the cover of the book. When I connect the Kindle to Calibre, the cover is synchronized but not the title. What I would expect is to see in the device the same title I see in Calibre, but that's not happening. I have tried several things with no success.

Could someone tell me how can I effectively change the title in the device and not only in Calibre with no need to delete it and send it again? Thanks!
