I created button in partner form to show another models relation with it. It is same button like Opportunities, Meetings, Sales button at partners form showing all its Opportunities, Meetings, Sales etc.

Code looks like this:

Action:

        <record id="action_calendar_service" model="ir.actions.act_window">
            <field name="name">Services</field>
            <field name="res_model">calendar.service</field>
            <field name="view_mode">tree,calendar,form</field>
            <field name="view_id" ref="view_calendar_service_tree"/>
            <field name="search_view_id" ref="view_calendar_service_search"/>
            <field name="help" type="html">
              <p class="oe_view_nocontent_create">
                Click to create new service.
              </p>
            </field>
        </record>   

inherited view:

        <record id="view_partners_form_service1" model="ir.ui.view">
            <field name="name">view.res.partner.form.crm.inherited1</field>
            <field name="model">res.partner</field>
            <field name="inherit_id" ref="crm.view_partners_form_crm1"/>
            <field eval="18" name="priority"/>
            <field name="arch" type="xml">
                    <button name="schedule_meeting" position="after">
                        <button
                            class="oe_inline oe_stat_button"
                            attrs="{'invisible': [('customer', '=', False)]}"
                            name="%(calendar_service.action_calendar_service)d"
                            icon="fa-star"
                            type="action"
                            context="{'search_default_partner_id': active_id}">
                            <field name="service_count" string="Services" widget="statinfo"/>
                        </button>
                    </button>
            </field>
        </record>

code in res.partner model:

class res_partner(models.Model):
    _inherit = 'res.partner'

    service_ids = fields.One2many('calendar.service', 'partner_id', 'Calendar Services')
    service_count = fields.Integer('Services', compute='_count_services')

    @api.one
    @api.depends('service_ids')
    def _count_services(self):
        self.service_count = len(self.service_ids)

So everything works, except it always opens all 'calendar.service' records without filtering with 'partner_id' (the one that button was pressed from). Is there something I miss?
