Please read the ajax() function documentation for proper usage:
http://web2py.com/books/default/chapter/29/11#The-ajax-function.
The ajax() function takes a URL as the first argument. Instead, you are
supplying the following string: *'order_update, vars=dict(id={{=p.id}},
qty={{=qty}})'*. I assume you want ajax('{{=URL('order_update,
vars=dict(id=p.id, qty=qty))}}', ...).
