drupal menu callback hook not calling function -

i using drupal 7. have link goes href="/mod/filter/1"

 <a href="/mod/filter/1">x</a> 

and have a hook_menu

 function mod_menu () {     $menu = array(                     'mod/filter/%' => array (                                     "title" => "bare html use in ajax.",                                     "page callback" => "mod_remove_filter_function",                                     "page arguments" => array(1),                                     "type" => menu_callback,                     )     );      return $menu;  } 

then callback function

 function mod_remove_filter_function($arg){     dsm('call filter');     drupal_goto('/res/search');  } 

to me should work, first time i've used menu hook looks should work according documentation given.

any ideas why doesn't work?

function mod_menu () {     $menu = array(                 'mod/filter/%' => array (                                 "title" => "bare html use in ajax.",                                 "page callback" => "mod_remove_filter_function",                                 "page arguments" => array(1),                                 "type" => menu_callback,                 )   );    return $menu;   } 

hook workds perfect. problem might in callback function dsm function requires devel module , if using drupal_goto('/res/search'); check "/res/search" path first .

:)  

here how use hook_menu in custom modules.

$menu['mod/filter/%'] = array(         'title'=>t('look title'),                     'page callback' => 'mod_remove_filter_function',         'access callback' => 'user_access',         'access arguments' => array('access_contents'),         'type' => menu_normal_item,     );
