Typeahead 0.9.3 autocomplete remote don't work properly

I'm using typeahead for an autocomplete field. When i use option remote like explaint here: https://blog.twitter.com/2013/twitter-typeaheadjs-you-autocomplete-me It show all entries and not the subset it should show. Here is the js code:

<script type="text/javascript">
jQuery(document).ready(function(){
  jQuery('#palettenNummerEinlagerung').typeahead({
    name: 'nummer',
    remote:'http://ift.tt/1R5cgso'
  });
});  
</script>

And the serverside action for the json wich should be recived remotely:

public function getPalettennummerEingelagert(){
    $result=\DB::table('paletten')
    ->leftJoin('einlagerungen', function ($join) {
        $join->on('paletten.id', '=', 'einlagerungen.palette_id');
    })
    ->whereNotNull('einlagerungen.palette_id')
    ->whereNull('einlagerungen.entahmedatum')
    ->where('nummer', 'LIKE', '%'.\Input::get('q').'%')
    ->select('nummer')
    ->get();
    $returnArr=array();
    for ($i=0;$i<count($result);$i++)
    {
            $returnArr[]=''.$result[$i]->nummer.'';
    }
    return json_encode($returnArr);
}
