Is it a ZEN Select component rather than just an html select?   If so, maybe set the displaylist and value via the ZEN helpers? 
From memory (and it has been a long time), something like:
var select = zen(zenIdOfSelect)
select.diplayList='one,two,three'
select.setValue(3)
select.refreshContents()

Quick note on one thing has come up a few times - the new view page does have a link to the home page. 

From any page, clicking the "I" icon in the top bar goes to the CCR home page, and the top option in the hamburger menu is "Home".
