Response from Generic Bulb Device

If I send the ON or OFF command to a Philips Hue bulb via " ```
http:///apps/api//devices//on or off?access_token=

then I get in the response on both attributes[1] and [2] only the value before execution of the command.
It would be very helpful to get in [1] the value before the execution and in [2] the value after the execution.
