When i check connection database using xmlrpc or jsonrpc the data will not update or be same before update but data in db updated so i will refresh browser for update ui data, how to fix it like example in test connection in outgoing email server

<buttonstring="Check API"name="check_api"type="object"class="btn-primary"attrs="{'invisible': [('selection_rpc', '==', 'local')]}"/>

def check_api(self):
host = self.fields_host
port = self.fields_port
db_name = self.fields_database
username = self.fields_username
password = self.fields_password

title = "Warning!"
message = "Database Disconnected, Please Check Username or Password!!"
type = 'warning'
try:
# if (self.selection_rpc == 'socketrpc'):
# odoo = odoorpc.ODOO(host, port=port)
# # # Login
# odoo.login(db_name, username, password)

# if (odoo.env.uid):
# title = "Success!"
# message = "Database Connected"
# type = 'success'
if (self.selection_rpc == 'xmlrpc'):
base_url = 'http://' + host + ':' + port + '/'

common = xmlrpc.client.ServerProxy(
'{}/xmlrpc/2/common'.format(base_url))
uid = common.authenticate(db_name, username, password, {})

if (uid):
title = "Success!"
message = "Database Connected"
type = 'success'
elif (self.selection_rpc == 'jsonrpc'):
url = "http://%s:%s/jsonrpc" % (host, port)
uid = self.call(url, "common", "login", db_name,
username, password)
if (uid):
title = "Success!"
message = "Database Connected"
type = 'success'
except Exception as e:
print("Except", str(e))
return False

return {
'type': 'ir.actions.client',
'tag': 'display_notification',
'params': {
'title': _(title),
'message': message,
'type': type,

}
}
