javascript keuzemenu kan niet onthouden

Als je in het bovenste veld iets invult, verschijnt dat ook bij de rest. Als je dan op "other" klikt in het menu, kun je ernaast iets anders invullen.

Dat wordt allemaal mooi naar de database gestuurd. Maar als ik dit wil updaten, dan zie ik alles zoals het was nog voordat je het kunt invullen. Het javascript begint gewoon opnieuw en onthoudt niet wat je eerst gekozen hebt. zeer vervelend als je iets wilt verbeteren.

Valt hier iets aan te doen?
