handler to add input into form component

Hi,
First of all thanks for previous prompt answers, they really help me to move forward.
I need to add/remove inputs dynamically to/from a form component by clicking on buttons. The true is I do not even know what would be the best way – sessions, ajax, persistent components? It would be essential if the form keeps values already filled in and just adds new input element. This will be a form user can configure himself – i.e. buttons like add text area, add text input and remove this input…
I was trying to do it via persistant component but I am not too sure if this is a way. It does not work anyways…
Presenter:

<?php
use Nette\Application\UI\Form;

/**
 * @persistent(form)
 */

class ConfiguratorPresenter extends BasePresenter
{
	public function startup()
	{
	  parent::startup();
	}

	protected function createComponentForm($name)
	{
	    $form = new Form(NULL, 'form');
	    $form->addText('initialInput','Initial Input');
	    $form->addSubmit('save', 'Save');
	    $form->onSuccess[] = callback($this, 'save');
	    return $form;
	}

	public function save(Form $form)
	{
		// do something
	}

	public function handleAddInput($name,$label) {
	    $this->form->addText($name,$label);
	}


	public function handleRemoveInput($name) {
	    unset($this->form[$name])
	}
}
?>

… and the manual form rendered would append <a href="{removeInput!, $name}">remove input</a> to every input.
Thanks for any advice.
