Callback_before_insert not working

Hi Grocery CRUD pro,

I was use callback_before_insert in "A" controller and its working. But after i copied "A" controller to "B" controller, is not working at all. Here's the code :



function tests_display(){

  $crud = new grocery_CRUD();

	    $crud->set_model('tests_crudmodel');

  $crud->set_theme('flexigrid');

	    $crud->set_table('tests');

	    $crud->set_subject('Soal Ujian');

 

  $crud->columns('date','information','class_id','question_id','percentage','total_qty','duration','maximum_value','maximum_skip','start');

  $crud->display_as('date','Tanggal Pembuatan');

  $crud->display_as('information','Keterangan');

  $crud->display_as('class_id','Untuk Kelas');

  $crud->display_as('question_id','Sumber Soal');

  $crud->display_as('percentage','Komposisi Soal');

  $crud->display_as('total_qty','Total Soal');

  $crud->display_as('duration','Durasi Soal (menit)');

  $crud->display_as('maximum_value','Nilai Maksimum');

  $crud->display_as('maximum_skip','Total Skip');

  $crud->display_as('start','Publish');

 

  $crud->fields('information','class_id','question_id','percentage','total_qty','duration','maximum_value','maximum_skip','start');

  $crud->required_fields('information','class_id','question_id','percentage','total_qty','duration','maximum_value');

  $dataclass = $this->classes->lists_array();

  $dataquestions = $this->classes->questions_lists_array();

  $datapercentage = array(100=>'100%',90=>'90%',80=>'80%',70=>'70%',60=>'60%',50=>'50%',40=>'40%',30=>'30%',20=>'20%',10=>'10%',0=>'0%');

 

  $crud->change_field_type('class_id','multiselect',$dataclass);

  $crud->change_field_type('question_id','multiselect',$dataquestions);

  $crud->change_field_type('percentage','multiselect',$datapercentage);

  $crud->change_field_type('total_qty','integer');

  $crud->change_field_type('duration','integer');

  $crud->change_field_type('maximum_value','integer');

  $crud->change_field_type('maximum_skip','integer');

  $crud->change_field_type('start','true_false');

  $crud->callback_before_insert(array($this, 'insert_data'));

 

  $crud->callback_add_field('start',array($this,'callback_edit_start'));

  $crud->callback_edit_field('start',array($this,'callback_edit_start'));

  $crud->set_rules('question_id', 'Sumber Soal','callback_simpan_sumber_soal');

  $crud->set_rules('percentage', 'Prosentase','callback_percentage_check');

	    $output = $crud->render();

	    $this->_crud_output($output);

}



function insert_data($post_array)

{

  $rs = $this->school_years->get_active_school_year();

  $post_array['school_year_id'] = $rs[0]['id'];

  $post_array['date'] = date('Y-m-d');

  $post_array['time'] = date('H:i:s');

  $post_array['ip'] = $_SERVER['REMOTE_ADDR'];

  //echo var_dump($post_array);

  return $post_array;

}

my temp solution is to embeed my callback_before_insert code into db_insert in my own model like these:



function db_insert($post_array)

    {

  $CI =& get_instance();

  $CI->load->model('school_years_model','school_years');

  $rs = $CI->school_years->get_active_school_year();

  $post_array['school_year_id'] = $rs[0]['id'];

  $post_array['date'] = date('Y-m-d');

  $post_array['time'] = date('H:i:s');

  $post_array['ip'] = $_SERVER['REMOTE_ADDR'];

 

  $insert = $this->db->insert($this->table_name,$post_array);

 

	 if($insert)

	 {

	  return $this->db->insert_id();

	 }

	 return false;

    }

Could anyone tell me, why it happens? Thanks for your kindly reply
