work around datachange_notification limitation

[HaythemLtifi]

hello folks, i made a simple code to get the values form a server when the values changes . the problem is i have 3 values that changes and i had a way to view them and display them .
i tried to call the " get_display_name() " method but it blocks the datachange_notification .......
this is my work around , even thew it works i think its not clean.
is there a cleaner way?
thanks

It isn't nice to use... You can probably learn stuff from #701 and #502 .
