Plugin events "onAfterOrderUpdate" and "onAfterOrderCreate" not working.

Hi,

I am trying to create a plugin where the order information will be sent to a 3rd party api after every successful order.

I know I can't use the OnAfterOderConfirm since that's only available for primary payment and shipping method plugins.

So, I wanted to use onAfterOrderUpdate function to catch all orders on update and it's not working as expected. I created a plugin for group hikashop, installed and enabled it and no avail.
PHP gist.github.com/chetanmadaan/7389c716c1edd3280c7228a25be1fa9a
XML: gist.github.com/chetanmadaan/d02ec03537f5f139dd364a71f58fdbc1

The file that triggers this plugin:
/administrator/components/com_hikashop/classes/order.php:474 does seem to have the correct trigger and if I print the $order there, it shows the array.

Can you see if I am doing anything wrong here?

Thank you,
Chetan

That did it. Thank You!
