(Laravel) method $ .get can not find route

Hey guys, all right?

I would really appreciate your help as I have been stuck with this problem for a couple of days and can not solve it myself.

I have a multi-line table with a checkbox on each line and a button that, when clicked, takes all the rows that are selected, stores the ids of those rows in an array, transforms the array into a json, and makes a request a route by passing this json, where it will be manipulated to go through all the ids and make changes to the database.

Initially it worked quietly, but for a while it stopped working, I do not know why.

JavaScript function (in the view):

    function tornarPendente() {

    var arrayIds = [];

    //pega todos os checkbox que estão selecionados e para cada um pega o ID referente ao aluno
    $.each($('.checkbox1').prop('checked', 'checked'), function() {
        var id = ($(this).attr('id'));
            arrayIds.push(id);  //coloca no vetor de ids
    });

    //converte o array em um json para passar para a rota
    var json = {
        "ids": arrayIds
    };

    $.get('../controle/concluidas/tornarTodasPendentes', json, function(data) {
        window.location.reload(true);
    });

}

Route

Route::get('/controle/concluidas/tornarTodasPendentes/', function() {
$input = Input::only('ids'); //recebe um array de ids
$input = $input['ids']; 
foreach($input as $id) {
    $aluno = new App\Aluno();
    $aluno = $aluno->where('id', '=', $id)->first();
    $aluno->pendente = '1';
    $aluno->save();
}
    return Redirect::back();    

});

NOTE: Strange is the fact that if I change the route address to a route that does not exist, javascript does not return any error (even if I remove the window.location.reaload (true) part) .

NOTE: If I give an alert (json ['ids']) I can see the ids normally.

Is there any way for me to know if these ids have at least reached the route?

Any kind of help is welcome.

Thank you!
