Drupal 7 hook_menu() throws a 404 - ajax

Question

I have tried to acces it through an ajax call and by simply going to it by url,
It always give me a 404
i have flushed my caches multiple times and even tried to remove and re-add the module (as i have had the problem with other modules and read on other responses on the problem)
i also have looked it up on internet, but i can't seem to find any solution
(module name : TTK_rest)
.module:
function TTK_rest_menu() {
$items = array();
$items['TTK_rest_api/TTK_task_progression'] = array(
'page callback' => 'TTK_task_progression_view',
'access arguments' => array('access content'),
'access callback' => TRUE,
'type' => MENU_CALLBACK,
);
return $items;
}
function TTK_task_progression_view(){
return '{"pom":"pom"}';
}
and the ajax call to it:
$.ajax({
url:'/TTK_rest_api/TTK_task_progression',
data: {"getProgress": "true"},//, "event_id":settings['TTK_task_progression']['jsEvent_id']
type: "POST",
contentType: "JSON",
success: function(data){
var $data = $(data);
console.log(data);
},
error: function(err){
console.log("neupe, try again");
}
});

Answer 1

finally found the solution (posted the question after multiple hours of searching, if i've known i would have find an answer this quick i wouldn't have asked it.. still going to leave it up with a response in case there is someone with the same problem
solution to the problem was that i had to have my function name had to have the module name prefix
note: i have an other module called 'TTK_task_progression', might be the origin of the problem i had
solution:
function TTK_rest_menu() {
$items = array();
$items['TTK_rest_api/TTK_task_progression'] = array(
'page callback' => 'TTK_rest_progression', // <- changed
'access arguments' => array('access content'),
'access callback' => TRUE,
'type' => MENU_CALLBACK,
);
return $items;
}
function TTK_rest_progression(){ // <- changed
return '{"pom":"pom"}';
}
