put method not working

I have this route for update my user data:

PHP Code:

$routes->put('/admin/users/(:num)/update', 'Admin\UserController::update/$1', ['as' => 'update']); 


in  UserController:

PHP Code:

    public function update(int $id){
        echo 'Ok';
    } 


in View:

PHP Code:

<form method="PUT" action="<?= route_to('update', esc($user['id'])); ?>" > 


But in Action i see error:

Code:

404 - File Not Found

Controller or its method is not found: {0}::{1}
