I need to extend part of point_of_sale js module (/point_of_sale/static/src/js/models.js) in odoo 10 in order to force it to load more fields from res.company model.

In base variant it looks like this:

odoo.define('point_of_sale.models', function (require) {
"use strict";
...
exports.PosModel = Backbone.Model.extend({
...
    models: [
        {
            model:  'res.company',
            fields: [ 'currency_id', 'email', 'website', 'company_registry', 'vat', 'name', 'phone', 'partner_id' , 'country_id', 'tax_calculation_rounding_method'],
            ids:    function(self){ return [self.user.company_id[0]]; },
            loaded: function(self,companies){ self.company = companies[0]; },
        }
    ]
})
})

While I need to add fields 'logo', 'city' the array fields.
I have tried lots of variants, the best result I got was with this solution:

odoo.define('my_module.models', function(require){
"use strict";

var core = require('web.core');
var modules = require('point_of_sale.models');

var _t = core._t;
modules.PosModel.include({    
        models: [
            { 
                model:  'res.company',
                fields: [ 'currency_id', 'email', 'website', 'company_registry', 'vat', 'name', 'phone', 'partner_id' , 'country_id', 'tax_calculation_rounding_method', 'logo', 'city'],
                ids:    function(self){ return [self.user.company_id[0]]; },
                loaded: function(self,companies){ self.company = companies[0]; },
            }
         ]
});
});

And everything I get for this is:

warning: Some modules could not be started
Missing dependencies:    Array [ "point_of_sale.models" ]
Non loaded modules:      Array [ "custom_receipt.models" ]
Debug:                   Object { custom_receipt.models: Object }

message in browser console. Can someone explain how to fix it, how to properly override JS in odoo 10 and why it doesn't see point_of_sale.models?
