Working example of Xamarin.Forms.Labs Autocomplete

Hi, I'm starting to experiment with XLabs. The example for Autocomplete has a comment in the XAML of "This isn't working yet".

https://github.com/XLabs/Xamarin-Forms-Labs/blob/master/Samples/XLabs.Sample/Pages/Controls/AutoCompletePage.xaml

Can someone please point me to a working example, preferably one that is a fully code-behind approach ?

Thanks!
