[quote author="johnpeace" date="1297667228"]You need to give your submit input a name attribute and value.[/quote]
Nopes thats not it and its not mandatory to have name or value in submit button. Input button does'nt work because there is no form so its not sending it.
You need to print the form_open() and form_close()

Code:

echo form_open_multipart('orders/change_status/'.$data->ORDER_ID);
...
echo form_close();
