Symfony2 - Twig Exception after changing package name

Question

I have a problem in Symfony 2.6.13. I created a special type GeneralBundle / Form / Type / DateRangeType.php:

<?php

namespace Ironstat\GeneralBundle\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class DateRangeType extends AbstractType
{
    const NAME = 'date_range';

    private $manager;

    public function __construct($manager) {
            $this->manager = $manager;
    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('dateFrom', 'date', array(
                'widget'        =>  'single_text',
                'format'        => 'dd/MM/yyyy',
                'attr'      => array('class' => 'datepicker input-small'),
                'label_attr'    => array('class' => 'control-label label-sm'),
                'label'     => 'Fecha desde',
                'empty_value'   => false,
            ))
            ->add('dateTo', 'date', array(
                'widget'        =>  'single_text',
                'format'        => 'dd/MM/yyyy',
                'attr'      => array('class' => 'datepicker input-small'),
                'label_attr'    => array('class' => 'control-label label-sm'),
                'label'     => 'Fecha hasta',
                'empty_value'   => false
            ));

            $transformer = new DateRangeTransform($this->manager);

            $builder->addModelTransformer($transformer);
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver) {
        $resolver->setDefaults(array(
            'data_class' => 'Ironstat\GeneralBundle\Entity\DateRange',
        ));
    }

    public function getName() {
        return self::NAME;
    }
}

So, according to the docs, I also create a service in GeneralBundle / Resources / config / services.yml:

services:
    ironstat.type.date_range:
        class: Ironstat\GeneralBundle\Form\Type\DateRangeType
        arguments: ["@doctrine.orm.entity_manager"]
        tags:
            - { name: form.type, alias: date_range }

I also add this configuration to config.yml:

twig:
    form:
        resources:
            - 'IronstatGeneralBundle:Form:Type:DateRangeType'

But, when I try to add it to my form, I got this error:

During template rendering, an exception was thrown ("Unable to load type 'date_range') in IronstatPacienteBundle: Page: edit.html.twig on line 27.

In my form, I add it like this:

$builder->add('cau'     , 'collection'  , $this->getDateRangeType());

, , , (, , ...). . ( ), , . bootstrap.php.cache, . , . "" "" .

UPDATE: appKernel.php:

public function registerBundles()
    {
        $bundles = array(
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),
            new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
            new Symfony\Bundle\AsseticBundle\AsseticBundle(),
            new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new Ironstat\PacienteBundle\IronstatPacienteBundle(),
            new Ironstat\DiagnosticoBundle\IronstatDiagnosticoBundle(),
            new Ironstat\EntidadBundle\IronstatEntidadBundle(),
            new Ironstat\usuarioBundle\IronstatusuarioBundle(),
            new Ironstat\GeneralBundle\IronstatGeneralBundle(),
            new Siphoc\PdfBundle\SiphocPdfBundle(),
            new FOS\UserBundle\FOSUserBundle(),
            new Ironstat\EnvioBundle\IronstatEnvioBundle(),
            new Ironstat\ArchivoBundle\IronstatArchivoBundle(),
            new Knp\Bundle\PaginatorBundle\KnpPaginatorBundle(),
            new Ironstat\ReporteBundle\IronstatReporteBundle(),
            new Knp\Bundle\SnappyBundle\KnpSnappyBundle(),
        );

getDateRangeType:

private function getDateRangeType() {
        return array(
            'type'      => 'date_range',
            'allow_add'     => true,
            'allow_delete'  => true,
            'attr'      => array('class' => 'datepicker input-small'),
            'label_attr'    => array('class' => 'control-label'),
            'empty_data'    => null
            );
    }
