iam using pure alpha 3  version,In my application, iam getting selectmenu options dynamically from json.

when i click at first time,my select menu is not populating its options..but,it is working when i click Back button

 and move to prev page and again come to same page and if i click selectmenu its populating its data.

can i know why the selectmenu is not populating its data at first click?
