Jquery Autcomplete showing an empty list

Using Jquery Autocomplete, requesting a script.

The list shows as many rows as there are results (when I set my script to return X results, there are X rows as well in the list) :

But it doesn't fill the rows with the data. What could have gone wrong there ?

---

The data returned is some json :

Request URL:http://localhost:8000/search/autocomplete?term=750
Request Method:GET
Status Code:200 OK
Remote Address:127.0.0.1:8000

And here is the data :

[{"zip":"75004","commune":"PARIS 04","libelle":"PARIS","lieudit":""},{"zip":"75005","commune":"PARIS 05","libelle":"PARIS","lieudit":""},{"zip":"75003","commune":"PARIS 03","libelle":"PARIS","lieudit":""},{"zip":"75006","commune":"PARIS 06","libelle":"PARIS","lieudit":""},{"zip":"75008","commune":"PARIS 08","libelle":"PARIS","lieudit":""},{"zip":"75012","commune":"PARIS 12","libelle":"PARIS","lieudit":""},{"zip":"75015","commune":"PARIS 15","libelle":"PARIS","lieudit":""},{"zip":"75016","commune":"PARIS 16","libelle":"PARIS","lieudit":""},{"zip":"75017","commune":"PARIS 17","libelle":"PARIS","lieudit":""},{"zip":"75010","commune":"PARIS 10","libelle":"PARIS","lieudit":""},{"zip":"75018","commune":"PARIS 18","libelle":"PARIS","lieudit":""},{"zip":"75001","commune":"PARIS 01","libelle":"PARIS","lieudit":""},{"zip":"75009","commune":"PARIS 09","libelle":"PARIS","lieudit":""},{"zip":"75014","commune":"PARIS 14","libelle":"PARIS","lieudit":""},{"zip":"75002","commune":"PARIS 02","libelle":"PARIS","lieudit":""},{"zip":"75007","commune":"PARIS 07","libelle":"PARIS","lieudit":""},{"zip":"75011","commune":"PARIS 11","libelle":"PARIS","lieudit":""},{"zip":"75013","commune":"PARIS 13","libelle":"PARIS","lieudit":""},{"zip":"75019","commune":"PARIS 19","libelle":"PARIS","lieudit":""},{"zip":"75020","commune":"PARIS 20","libelle":"PARIS","lieudit":""}]

Here is my JS :

$(function(){
     $( "#fromzip" ).autocomplete({
        source: "/search/autocomplete",
        dataType: 'json',
        minLength: 3,
     });
  });

The HTML :

<input 
      id="fromzip"
      name="fromzip"
      type="text"
      class="form-control"
      placeholder="69003"
      pattern=".{5}"
      title="5 numbers zip"
      maxlength="5"
      required >

And the PHP (Laravel Input, DB and Response facades) :

public function autocomplete(){
        $term = Input::get('term');
        $results = array();

        $queries = DB::table('zips')
          ->where('zip', 'LIKE', $term.'%')
          ->orWhere('libelle', 'LIKE', $term.'%')
          ->take(30)->get();

        foreach ($queries as $query)
        {
            $results[] = [ 'zip' => $query->zip,
            'commune' => $query->commune,
            'libelle' => $query->libelle,
            'lieudit' => $query->lieudit];
        }

        return Response::json($results);

      }
