On Android, when binding the Text value to a view model property, the value doesn't update.

Use the following to reproduce:

// VIEW

<Label Text="RadEntry" />
<telerikInput:RadEntry x:Name="MyRadEntry" 
                       Text="{Binding Username}" 
                       Margin="0,0,0,20"/>
        
<Label Text="Xamarin.Forms Entry" />
<Entry Text="{Binding Username}"/>

// VIEW MODEL

public class ViewModel : NotifyPropertyChangedBase
{
    private string username = "initial";
    private int counter;

    public ViewModel()
    {
        Device.StartTimer(TimeSpan.FromMilliseconds(500), (() =>
        {
            counter++;
                
            Device.BeginInvokeOnMainThread(() =>
            {
                Username = $"{counter}";
            });
                
            return counter < 100;
        }));
    }

    public string Username
    {
        get { return username; }
        set { username = value; OnPropertyChanged();}
    }
}
