Premazanie hodnôt formulára po odoslaní

Nevie niekto poradiť ako premazať hodnoty formulára po jeho odoslaní ? Skúšal som nastaviť defaults v tovarničke aj v proces form aj v create form ale nič nezabralo.

A ešte mám jednu otázku, renderujem daný formulár dva krát, a keď ho odošlem, hodnoty sa nastavia v obidvhoch a tak isto majú obidva rovnaké id (toto som vyriešil tak že som v template každému inputu manualne prestavil id, ale ak existuje lepší spôsob, sem s ním)

<?php
namespace App\Suggester\Forms;


use Nette\Application\UI\Form;
use Nette\Application\UI\Control;

class CustomCategoryUpdateFormFactory extends Control
{
    /**
     * @var \App\Suggester\Models\Suggester_categoryRepository
     */
    private $suggesterCategoryRepository;

    /**
     * @var \App\Suggester\Models\Suggester_typeRepository
     */
    private $suggesterTypeRepository;

    public function __construct(
        \App\Suggester\Models\Suggester_categoryRepository $suggesterCategoryRepository,
        \App\Suggester\Models\Suggester_typeRepository $suggesterTypeRepository
    ) {
        parent::__construct();
        $this->suggesterCategoryRepository = $suggesterCategoryRepository;
        $this->suggesterTypeRepository = $suggesterTypeRepository;
    }

    public function create()
    {
        $form = new Form;

        $form->addHidden('id', 'id')
            ->setDefaultValue("0");

        $form->addText('name', 'name')
            ->setDefaultValue("")
            ->setRequired(TRUE);

        $form->addSelect('type_id', 'type', $this->suggesterTypeRepository->all->fetchPairs('id', 'name'))
            ->setDefaultValue(1)
            ->setRequired(TRUE);

        $form->addSubmit('submit', 'submit');

        $form->onSuccess[] = $this->process;

        return $form;
    }

    public function process(Form $form)
    {
        $values = $form->getValues();

        $this->suggesterCategoryRepository->update($values);

        $form->setDefaults(array(
            'id' => "0",
            'name' => '',
            'type_id' => 1,
        ));
    }
}
