Using sequences in Odoo 9

Question

I'm experimenting with sequences and handle widge, I'm using two test models to make it work

Country

# -*- coding:utf-8 -*-
from openerp import models,fields,api
class t_country(models.Model):
        _name           =   "t_country"
        _rec_name       =   "description"
        _order          =   "description"

        description     =   fields.Char(string="description",required=True)
        states          =   fields.One2many('t_states','country_id',string="states")

States

# -*- coding:utf-8 -*-
from openerp import models,fields,api
class t_states(models.Model):
        _name           =   "t_states"
        _rec_name       =   "description"
        _order          =   "sequence"

        description     =   fields.Char(string="description",required=True)
        country_id      =   fields.Many2one('t_country',readonly=True,  string="country")
        sequence        =   fields.Integer(readonly=True,string="sequenece")

And I've been added the following line to my view

<field name="sequence" widget="handle" string="sequence"/>

But when I move the different records on the model their sequence numbers are not ordered as they have to.

The widget needs to be used with a function to change the sequence id's correctly?

EDIT

Added a image of a test screen

I tried removing the readonly arg from my sequence butstill have the same result. The only way to get the correct sequence with my code its moving a item to the first position to the list, then the rest of the sequence get calculated in order

Your sequence is in readonly, You cannot modify the value of the sequence.
