What's the proper way to handle transaction and after hooks?

[Falci]

I have an event in my app that updates the balance inside a transaction:

sequelize.transaction(async t => {
  await updateBalance(t);
  await Payment.bulkCreate({...}, {
    updateOnDuplicate: [...], transaction: t
  });
});

The Payment has a afterBulkCreate hook to send an email with the latest 5 payments.

The problem I'm facing is: the select inside the hook is not getting the latest payment.
I suspect it could be related to the transaction: the hook was triggered but the transaction was not committed yet, so the select don't get it. Does it make sense?
If so, what can I do ? Can I delay the hook for after the transaction commit ?

I found a fix:

1. move the content of the hook to a static method
2. use an unmanaged transaction and manually commit it
3. after the commit call the static method from step 1.
