How to set Teams for Email using Hook

[override]

Hi,

How to set Teams in Email using Hook?
I have tried something like this in afterSave

$entityManager = $this->getEntityManager();
$allTeams = $entityManager->getRepository('Team')->getAll();
$entity->set('teams', $allTeams->current()->get('id'));
$entityManager->saveEntity($entity, array('SkipAll' => true));

It doesn't set new team.
It should work in beforeSave also by just avoiding saveEntity, just calling set?

[override]

Ok, I've used 'teams' instead of 'teamsIds' which was mistake.
