Im trying to add a sequence field to the crm.lead model. I have implemented this code for another custom module I built previously with no issues.

Ive added the new field

 class vox_crm_register(models.Model):
   
    _inherit = 'crm.lead'

    name_seq = fields.Char(
        string='Registration Reference',
        required=True,
        copy=False,
        readonly=True,
        index=True,
        default=lambda self: _('New'))
   

Ive overwritten the create function

@api.model
    def create(self, vals):
        print(vals.get('name_seq'))
        if vals.get('name_seq', _('New')) == _('New'):
            print('IF is true')
            vals['name_seq'] = self.env['ir.sequence'].next_by_code('vox_crm_register.sequence') or _('New')
        res = super(vox_crm_register, self).create(vals)
        return res

and this is my sequence

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <data noupdate="1">

        <record id="registration_sequence" model="ir.sequence">
            <field name="name">Registration Sequence</field>
            <field name="code">vox_crm_register.sequence</field>
            <field name="prefix">reg</field>
            <field name="padding">3</field>
            <field name="company_id" eval="False"/>
        </record>

    </data>
</odoo>

the result from the print statements in the create function  are

None
IF is true

because its inherited do I have to force it in someway or add a context???

Any help appreciated
