cordova - Windows phone dropdownlist choose options not showing current selected option -

i working on windows phone 8.1 universal app using cordova. getting weird issue while working dropdownlist.

when tap on dropdownlist open choose item screen can select item. screen shows options start not selected option.

for example have year dropdownlist start option 2001 2050. , have selected year 2025 whenever open dropdownlist shows 2001 not 2025.

you need save selected option in local settings , read when open "choose item" screen. this:

windows.storage.applicationdata.current.localsettings.values["year"] = "2002";
