RequireJS: How to transfer variables from one file to another?

Question

I use require with basic + basic forms. I am currently using RequireJS to split code into multiple files. I have models stored in separate files and you want to save the form validators separately.

However, I cannot access the variables defined in one file in another file, which depends on this. I get it Uncaught ReferenceError: isEmptyName is not defined. isEmptyNamedefined in validators and used in the model. Any feedback on RequireJS configuration is also welcome.

My configuration:

requirejs.config({

//By default load any module IDs from js/lib

baseUrl: 'js',

paths: {
     jquery: 'lib/jquery',
        app: 'lib/app', 
     wizard: 'lib/jquery.bootstrap.wizard.min',
  bootstrap: 'lib/bootstrap.min',
 underscore: 'lib/underscore-min',
   backbone: 'lib/backbone-min',
backboneForms: 'lib/backbone-forms.min',
langSwitcher: 'lib/lang',
     cookie: 'lib/cookie',
 datepicker: 'lib/bootstrap-datepicker',
       mask: 'lib/jquery.maskedinput.min',
 validators: 'modules/validators',  

  // models

personalData: 'models/personal-data',
addressData: 'models/address-data',
   workData: 'models/work-data',
productsData: 'models/products-data',
statmentData: 'models/statment-data',    

     model: 'models/form',
collection: 'collections/form',
      view: 'views/form',

     setup: 'setup',
      send: 'send',

},
    shim: {
    'underscore': {
        deps: ['jquery'],
        exports: '_'
    },  
    'backbone': {
        deps: ['underscore', 'jquery'],
        exports: 'backbone'
    },

    // all model needs to go within one collection

    'bootstrap' : ['jquery'],
    'wizard': ['jquery'],
    'backboneForms': ['backbone'],
    'validators': ['backbone','mask'],
    'personalData' : ['backbone','backboneForms','validators'],
    'addressData': ['backbone','backboneForms'],
    'workData': ['backbone','backboneForms'],
    'statmentData': ['backbone','backboneForms'],

    //'collection': ['backbone','backboneForms','personalData'],
    //'view': ['backbone','backboneForms','personalData']
 } 
});

Start validators.js

require(['backbone','backboneForms'], function(){


var lettersOnly = /^[A-Za-zęóąśłżźćńĘÓĄŚŁŻŹĆŃ]+$/;
var lettersOnlyDash = /^[A-Za-zęóąśłżźćńĘÓĄŚŁŻŹĆŃ\-]+$/;
var err = {};
var errCh = {};
var errFormat = {};

var isEmptyName = function(value){
err = { message: 'Wpisz imię.'};
if (value.length === 0) return err;
};

The beginning of model.js, which needs validators in validators.js

require(['backbone','backboneForms','mask','validators'], function(backbone,backboneForms,mask,validators){

var PersonalData = Backbone.Model.extend({

schema: {
    first_name:{ 
        title: 'Imię',            
        validators: [isEmptyName, isLetter, minCharCount] //Accessing validators.js members here...
    }, ...
