Is there any way to change the background color of the scroller on iOS 9?

I'm trying to change the background color of the HTML select element from the default dark gray on iOS 9 to white. I stumbled across this Phonegap/Cordova plugin: https://github.com/EddyVerbruggen/iOSWebViewColor-PhoneGap-Plugin but I'm not having much luck making it work. Any one else able to get this working on iOS 9?

I tried the sample code in my Ionic project, but there's no effect.

window.plugins.webviewcolor.change('#FFFFFF')

Here's what I've tried:

• Modifying theWebView.backgroundColor on line 107 in
  MainViewController.m
• Modifying the MainViewController.xib file and unchecking Opaque.
• Modifying the Objective-C code of the Cordova plugin to force
  [UIColor whiteColor]

Nothing works.
