how to display count_all_results record to view

Hi I am having trouble echoing a count to my view.

Please help. I am trying to count the number of subjects in the database.

Model:

PHP Code:

  public function Gettotsubjects($session_id, $section_id, $class_id) 
    {
        $this->db->select('subject_id');
        $this->db->where('session_id', $session_id);
        $this->db->where('section_id', $section_id);
        $this->db->where('class_id', $class_id);
        $this->db->distinct();
        return $this->db->count_all_results('ftscores_primary');
    } 


Controller:

PHP Code:

  public function Gettotsubjects($session_id, $section_id, $class_id)
     {
    $data = $this->ftprimary_model->Gettotsubjects($session_id, $section_id, $class_id); 
    return $data->subject_id;
         
    } 


View:

PHP Code:

<?php echo $CI->Gettotsubjects($value->session_id, $value->section_id, $value->class_id);?>

Nothing shows in the view even though it works well when I test in the Controller
