Here is what I want to do:

in the invoice screen, when creating new invoice, we select partner (customer or supplier). when you start typing characters the system bring partner name starting with those characters. I want the system to search not only name but also partner_code (this column I added to res.partner). So, the solution I though about is to override the display_name which is a compute field to make ti include both partner_code and name, instead of name only. i linked the display_name field with a compute method. But, my problem is that compute method is not triggered at all.

Please help me find out why it is not triggered.

here is the code:
