Odoo on button click open popup window and text in it

Question

I'm having Odoo workflow with Cancel and Reset buttons. I need that user on these buttons clicks can add a reason.

For that I found sale_cancel_reason app. Example here:

But I need everytime to write new reason, not select from list. I tied to make many2one relation to wizzard that user everytime can write reason on popup wizzard window:

cancel_id = fields.Many2one('sale.order.cancel', string="Cancellation")

'sale.order.cancel' - wizzard object

But then I got error:

AssertionError: Many2One relationships from non-transient Model to TransientModel are forbidden

As I understand I can't use Many2one relation with wizzard object. But how else can I make popup window with writable reason field? Is there any ways to do that?

what is your problem exactly is the selection if is that than the first answer is what you need — Charif DZ

Edit sale_cancel_reason\wizard\cancel_reason_view.xml file and change:

<field name="reason_id" widget="selection"/>

To

<field name="reason_id"/>

Update:

To create a new reason each time you click cancel button use this sale_cancel_reason

changed reason_id (Many2one) to reason (Char)

Odoo on button click open popup window and text in it
