What's the right way to use DOM with DataObjectDecorator

I have this piece of code in my decorator, which is mostly copy-paste from FormScaffolder to add a field for the many_many attribute Contacts.

public function updateCMSFields(FieldSet &$fields) {
   $component = 'Contact';
   $relationship = 'Contacts';
   $relationshipFields = $this->getRelationshipFields();
   $filterWhere = $this->owner->getManyManyFilter($relationship, $component);
   $filterJoin = $this->owner->getManyManyJoin($relationship, $component);

   $dom = new DataObjectManager($this->owner,
   $tab = $fields->findOrMakeTab('Root.Main.Contacts',

Existing contacts show up in the field as expected. But if I add a new contact, the contact it is saved in the Contact table, as expected, but the relation is not saved in the relationship table. If I replace DataObjectManager with ComplexTableField it works as it should.
