I am trying it, after applying the breakpoint on onchange function, it is not coming on the function in debug mode, code is below

from odoo import api, models, fields

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

    is_patient = fields.Boolean('Patient')
    is_doctor = fields.Boolean("Doctor", default=False)
    is_nurse = fields.Boolean("Nurse", default=False)
    is_institution = fields.Boolean("Institution", default=False)
    is_person = fields.Boolean("Person", default=False)
    is_insurance_company = fields.Boolean("Insurance Company", default=False)
    is_pharmacy = fields.Boolean("Pharmacy", default=False)
    num = fields.Integer("Integer")

    @api.depends('is_patient')
    def _onchange_insert_remove(self):
        print("ddddddddd")
        print("sssvsvsvs")

Please help me out in it
