How to show a popup modal in codeIgniter?

I have written a javascript click function to a class to display a popup when the relevant class be clicked. When i just put an alert it gives me the correct output. but the popup modal is doesn't show up

Model
I am using following model function

function get_reservation($type, $title, $date_cal)
{
    $this->db->select('reservations.*');
    $this->db->from('reservations');
    $this->db->where('(reservations.type like "' . $type . '%" and reservations.title like "' . $title . '%" and reservations.date_cal like "' . $date_cal . '%" )');
    $this->db->where('is_deleted', '0');

    $query = $this->db->get();

    return $query->result();
}

And i am calling that method in the following controller funtion

Controller

function get_reservations_records()
{        
    $this->load->model('mycal_model');

    $type = $this->input->post('type', TRUE);
    $title = $this->input->post('title', TRUE);
    $date_cal = $this->input->post('date_cal', TRUE);

    $data['reservation_records'] = $this->mycal_model->get_reservation($type,$title,$date_cal);

    echo $this->load->view('reservation_list_view', $data);     
}

Here i am passing data to another view. and i am calling that method in the javascript.

View

            </div>           


        </div>

    </body>
</html>

My popup doesn't show up. But when i put an alert and check it gives me the correct output. I can't figure out what is wrong with this. If anyone has an idea it would be a help.

Solution

You are including jQuery more than once, you have actually included jQuery in your head section, remove those two before your custom javascript, that's why you are getting $(...).modal is not a function error:

<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
