I've added Two fields into res.partner model and i want to show them on the POS receipt

i loaded the newly created field using:

odoo.define('pos_receipt.pos_order_extend', function (require) {
   var models = require('point_of_sale.models');

   models.load_models({
    model:  'res.partner',
    fields: ['houseNumber'],
    loaded: function(self , houseNumber){
        self.houseNumber = houseNumber;
        console.log(self.houseNumber);
    },
});

and the inherited receipt Xml is


<div t-if="env.pos.get_client()">

    Building :

    <t t-esc="env.pos.get_client().houseNumber"/>


</div>
