Autocomplete - trigger change in hidden field

Suitecrm version 7.10.25

I have a custom module that is related with module accounts.

In editview it shows the related field account with autocomplete and it works ok.

The problem is that i need to had a jquery change function to this field.

This field has also an input hidden that receives the id of the selected account.

The change function doesn’t trigger if the field is filled with autocomplete.

Anyone knows where is suitecrm file that do this?

I want to had a trigger change to this hidden field after the value is set so the jquery change function works.
