dynamically creating inputs with CakePHP and jQuery

index.ctp

<?php
	echo $this->Form->create('Usuario');
	echo $this->Form->input('Usuario.0.nome', array('div'=>array('id' => 'botoes-wrap')));
	echo $this->Html->link('mais um nome', '#botao-add-nome', array('id' => 'bota-add-nome'));
	echo $this->Form->submit('Enviar');
	echo $this->Form->end();

	echo $this->Html->script(array(
		'http://code.jquery.com/jquery.min.js',
		'usuarios/index'
	));
?>

<script type="text/template" id="template-inputs">
	<?php echo $this->Form->input('Usuario.::num.nome', array('div' => false, 'label' => '::plus° Nome')); ?>
</script>

index.js

;(function($, window, document, undefined) {
	$(document).ready(function() {
		var botaoAdd = $('#bota-add-nome'),
			botoesWrap = $('#UsuarioIndexForm').find('#botoes-wrap'),
			template = $.trim($('#template-inputs').html()),
			nextItem = 1;
		
		function addNewInputToTheForm() {
			var newItemHtml = template.replace(/::num/g, nextItem++)
                                              .replace(/::plus/, nextItem);

			botoesWrap.append(newItemHtml);
		}

		botaoAdd.on('click', function(e) {
			e.preventDefault();
			addNewInputToTheForm();
		});

	});
})(jQuery, window, document);

UsuariosController.php

<?php

/**
* Controller de usuários
*/
class UsuariosController extends AppController
{
	public function index()
	{
		if(isset($this->request->data) && $this->request->is('post')) {
			debug($this->request->data);
		}
	}
}

Olá, está funcional este código ?
