Laravel 5 method does not exist in Controller while used PHP __callStatic method -

i using laravel 5.2 on php 5.5.9

instead of hard coding methods in following controller, used php __callstatic method dynamically add functionality. works fine while tried console while calling methods route, getting following error

method app\http\controllers\showcategory::latest() not exist

here route

route::get('category/{id}',               'showcategory@latest'); 

here controller

class showcategory extends controller {  public $methods = [     'latest'        => 'created_at',      'newarrival'    => 'created_at',      'mostviewed'    => 'views' ];  public function get( $link_or_id, $orderby = 'created_at' ) {  }  public static function __callstatic($func, $arg) {      $category = new self();      if( array_key_exists( $func, $category->methods ) )     {          return $category->get( $arg[0], $category->methods[ $func ] );      }  }   } 

any point messed ?

__callstatic() triggered when invoking inaccessible methods in static context.

showcategory::latest(); works

and logically how put latest method in routes , know if found or not, if put in routes must found in controller
