Realm IList not updating UWP ListView - list

Question

I am just converting and app from C#/WPF to C#/UWP (Windows 10) and it seems that IList does not update the UWP ListView.
So first question - should it ?
and if not then how should I bind the IList property to ensure the ListView will update if items are added or removed?
Maybe some more context - new items are getting created on a background thread - and the exact same method/code seems to work fine with C#/WPF.
<ListView x:Name="siteListView" SelectionChanged="SiteListView_SelectionChanged"
DataContext="{x:Bind _this}"
ItemsSource="{x:Bind Customer.items, Mode=OneWay}" >
public class Customer : RealmObject
{
[PrimaryKey]
public string id { get; set; } = Guid.NewGuid().ToString();
public string name { get; set; }
public string address { get; set; }
public string contact { get; set; }
public float complianceScore { get; set; }
public string completionStatus { get; set; }
public IList<Site> sites { get; }
}

So it seems Realm IList does not implement the IList interface because of some conflicts with Android and as a result UWP bindings won't work. BUT I found a relatively simple solution. https://github.com/realm/realm-dotnet/issues/1575
public partial class SimpleList : ContentPage
{
ObservableCollection<Item> observableItems = new ObservableCollection<Item>();
IRealmCollection<Item> rawItems;
public class SimpleList()
{
InitializeComponent();
rawItems = realm.All<Item>().AsRealmCollection();
foreach (Item item in rawItems)
{
observableItems.Add(item);
}
rawItems.SubscribeForNotifications((sender, changes, error) =>
{
if (changes != null)
{
foreach (int i in changes.DeletedIndices)
{
observableItems.RemoveAt(i);
}
foreach (int i in changes.InsertedIndices)
{
observableItems.Insert(i, rawItems[i]);
}
foreach (int i in changes.ModifiedIndices)
{
observableItems.RemoveAt(i);
observableItems.Insert(i, rawItems[i]);
}
}
if (error != null)
{
// TODO: Handle Exceptions
}
});
MyListView.ItemsSource = observableItems;
}
async void Handle_ItemSelected(object sender, ItemTappedEventArgs e)
{
if (e.Item == null)
{
return;
}
// DO Stuff
// Deselect Item
((ListView)sender).SelectedItem = null;
}
}
