/* Fire the onchange event */
if ($select[0].selectedIndex != $(this).attr('index') && $select[0].onchange) {
$select[0].selectedIndex = $(this).attr('index');
$select[0].onchange();

now simply add the following below that line:/* Fire the change event */

$($select[0]).trigger('change');

A South African person identification number is a 13-digit number containing only numeric characters, and no whitespace, punctuation, or alpha characters.
It is defined as YYMMDDGSSSCAZ:
Using ID Number 8001015009087 as an example, it would read as follows using the old SA ID methology:
- YYMMDD represents the date of birth (DoB);
- GSSS is a sequence number registered with the same birth date (where G is 0-4 for females, 5-9 for males);
- C is the citizenship with 0 if the person is a SA citizen, 1 if the person is a permanent non-SA citizen;
- A currently 8 or 9 apply, however previously this number was the used in combination with Z to provide race and status.
- Z is a government control digit, 7 if the person is registered for National service and has completed it. 3 if the person has not completed the national service;
The ID indicates that a white SA citizen male was born on 1 January 1980, he was the 9th person to be registered and issued with an ID with the same birth date. He has been registered to do his national service with the defense force, and has completed the service.
As national service call up no longer exists the last digit no longer carries the same weight as in the past. And with the new IDs issued it is used as a control number to validate the ID.\
