generated url by paginator is not right in ZF2 - pagination

Question

I come across an issue with ZF2 Paginating. The generate url by paginator is not correct. Could anyone help point wrong place in my configuration? I just made small change for example in page:
http://framework.zend.com/manual/2.2/en/modules/zend.paginator.usage.html
Below is my change: module.config.php:
'routes' => array(
'shop' => array(
'type' => 'Literal',
'options' => array(
'route' => '/shop',
'defaults' => array(
'__NAMESPACE__' => 'Shop\Controller',
'controller' => 'Index',
'action' => 'index',
),
),
'may_terminate' => true,
'child_routes' => array(
'paginator' => array(
'type' => 'segment',
'options' => array(
'route' => '/index/list[/page/:page]',
'defaults' => array(
'page' => 1,
),
),
),
'default' => array(
'type' => 'Segment',
'options' => array(
'route' => '/[:controller[/:action][/:id]]',
'constraints' => array(
'controller' => '[a-zA-Z][a-zA-Z0-9_-]*',
'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
),
'defaults' => array(
),
),
),
),
),
),
'view_manager' => array(
....
'template_map' => array(
...
'index/page' => __DIR__ . '/../view/shop/index/page.phtml',
),
'template_path_stack' => array(
__DIR__ . '/../view',
),
),
In the IndexController:
public function listAction(){
$array = array(
0 => array('id'=>1, 'name'=>'samsonasik'),
.......
);
$paginator = new \Zend\Paginator\Paginator(new \Zend\Paginator\Adapter\ArrayAdapter($array));
$paginator->setCurrentPageNumber($this->params()->fromRoute('page'));
$paginator->setItemCountPerPage(1);
$vm = new ViewModel();
$vm->setVariable('paginator', $paginator);
return $vm;
}
For the list.phtml:
<?php echo $this->paginationControl($this->paginator,
'Sliding',
'index/page', array('route' => 'shop/paginator')); ?>
The script type index/pgae is mapped to page.phtml. I tried all three example controls in:
http://framework.zend.com/manual/2.2/en/modules/zend.paginator.usage.html#example-pagination-controls and changes arguments of $this->url() but all fail. For example, for search pagination, I change all:
$this->url($this->route, array('page' => $this->previous));
to
$this->url($this->route, array('controller'=>'index','action'=>'list','page' => $page));
For page:HOST/shop/index/list, all href of 2,3..and next in pagination control point to
HOST/shop/index/list/page/2 HOST/shop/index/list/page/3
This is what I expected, but this url matches shop/default instead of shop/paginator
Now the problem become simple:
how to write shop/paginator router so that url HOST/shop/index/list/page/2 can be matched:
'paginator' => array(
'type' => 'segment',
'options' => array(
'route' => '/index/list[/page/:page]',
'defaults' => array(
'page' => 1,
),
),
),
'default' => array(
'type' => 'Segment',
'options' => array(
'route' => '/[:controller[/:action][/:id]]',
'constraints' => array(
'controller' => '[a-zA-Z][a-zA-Z0-9_-]*',
'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
),
'defaults' => array(
),
),
),
