evalJS returns nothing on iOS, but works on Android

Fairly simple question. I'm trying to evalJS the document object for testing evalJS on my webview which is loaded to a remote webpage.

var test = $.webview.evalJS("document");
alert("DATA: " + test);

DATA:

Does evalJS not work with iOS? I tested this on both a physical device and simulator both have the same result (nothing in the data from evalJS).

Titanium SDK 3.5.0 iPhone 4S iOS 7 (physical) iPhone 5 iOS 8.1 (simulator)
