jQuery UI Autocomplete with CI ??

[eluser]LeonLanford[/eluser]
Hi, I'm new to codeigniter and ajax+jquery.
I'm now trying to implement the autocomplete jquery ui but I got a problem.

If the search doesn't return any result, the loading image is still there. (first image)
If the search return result but then I put more characters then the box will stuck there and the loading image still there. (second image)

The image only will be gone if I choose a returned result.
This doesn't occur if I don't use codeigniter.

My controller code

Code:

function search()
    {
        $kalimat = $this->input->post('term');
        
        $dorong_array = array();
        $dorong_array['respon'] = 'false'; //Set response
        
            $this->load->model('submit_model');
            $query = $this->submit_model->get_search_like("global_genre", "nama_gg", $kalimat, 0);
            
            
            
            if (!empty($query))
            {
                $dorong_array['respon'] = 'true'; //Set response
                $dorong_array['mesej'] = array();
                
                for($i=0; $i<count($query); $i++)
                {
                    foreach ($query[$i] as $key => $value)
                    $dorong_array['mesej'][] = array('label'=> $value, 'value'=> $value); //Add a row to array
                }
            }
        
            echo json_encode($dorong_array);
    }

My javascript code in view

Code:

$(function() {
    function log( message ) {
        $( "<div/>" ).text( message ).prependTo( "#log" );
        $( "#log" ).attr( "scrollTop", 0 );
    }
        
    $( "#term" ).autocomplete({
        source: function(request, response) {
            $.ajax({
                url: '&lt;?php echo site_url('submit/search');?&gt;',
                data: request,
                dataType: "json",
                type: "post",
                success: function(data){
                    if(data.respon =='true'){
                           response(data.mesej);
                     }
                }
            });
        },
        minLength: 1,
        select: function( event, ui ) {
            log( ui.item ?
            "Selected: " + ui.item.value + " aka " + ui.item.id :
            "Nothing selected, input was " + this.value );
        }
    });

Hope someone can help me,
Thanks
