I am filling the list of items of Spinner control 2 on value change event of spinner control 1.
There is a method for the onValueChange event of Spinner control 2.
OnValueChange event of control 1 fetches list for control 2 and set it. Then Control2 onValueChange event fires.
If the list is the same as the existing list of Control 2 then control2 onValueChange does not fire. Each time Control 1 on value change event fires, I want control2 onValueChange event to be changed.
