How to link work items to GIT commits after the commits and push operation

Hi all,
please, I would like to know if I can link my Work Item to the GIT Commit, after I've done the Push operation.
I've tried using the Note applied to a spscific Commit (<commit-sha1>), following the Wiki https://jazz.net/wiki/bin/view/Main/RTCGitNotes4WICommitLinking
but the WI in the note (after or before the Push operation) never is linked to my Work Item.
Only using the message in the Commit operation, I'm able to rigth link my Work Item.

Please, can you help me?

Many thanks in advance.
Alberto
