The image is not shown.  Anyway, it is a combination of _defaults value (and overriding the default_get method of ORM) and on_change on the fields that are given _defaults.

You could use context to set the values of the fields at one2many field
In res.partner table, odoo uses context to pass the values of Company to its Contacts.  Refer: https://github.com/odoo/odoo/blob/8.0/openerp/addons/base/res/res_partner_view.xml#L191 [1]

context={'default_country_id':country_id}

*(*) default_*FIELDNAME ==> set value for your particular field
*(*) search_default*_FILTERNAME ==> sets the search filter by default
