Hi everyone, 

I added an one2many field to a base model related to a custom model that I created.

In the form view of the base model I want to be able to create some records of the custom model.

this is the form view of the model, I want the "Products" page that I created to have the "add a line" button.

But this is my result:

I edit the view from development mode, and the two pages are structured as the same way:

And I think the model is fine:

I'm running an Odoo Community v13 instance. 

I don't know what I'm doing wrong, if somebody could help me I would really appreciate it!

Thanks in advance!
