execute function using Ext.Loader.setConfig with ExtJS

Question

Im trying to create a path with ExtJS using Ext.Loader.setConfig, im following the example from Api Docs but every time i try to execute the method holaMundo not works and not show any error.

This is the code of NombreClase.js in js/pruebapath/miprueba/

Ext.define('js.pruebapath.miprueba.NombreClase', {
    constructor : function () {
        return this
    },
    holaMundo : function () {
        alert("¡¡Hola Mundo!!");
    }
});

This is the code of app.js

Ext.Loader.setConfig({
    enabled : true,
    paths : {
        'modelo' : "js/pruebapath/miprueba"
    }
});

Ext.require('modelo.NombreClase');

Ext.onReady(function () {
    var prueba = Ext.create('modelo.Nombreclase');
    prueba.holaMundo();
});

I tried to change the code of NombreClase.js to Ext.define('modelo.NombreClase', { shows an error.
