Answer 1

Your code is not working Because you are not return any data from model
public function get_data()
{
if($_POST['type'] == 'patient_table'){
$row_num = $_POST['row_num'];
$result =$this->db->query( "SELECT patientId, fname, nic, tpnumber FROM tblpatient where name LIKE '".strtoupper($_POST['name_startsWith'])."%'");
$data = array();
while ($row = mysqli_fetch_assoc($result)) {
$name = $row['patientId'].'|'.$row['fname'].'|'.$row['nic'].'|'.$row['tpnumber'].'|'.$row_num;
array_push($data, $name);
}
return $data;// return your data
}
}

Answer 2

You have to set type:"POST" in ajax call otherwise it will take it as GET so add the type in your $.ajax call like,
$.ajax({
url:'...',
type:"POST",// add this line in your ajax call
....
})
