When using TwoWay binding for AutoComplete on iOS, the Text is cleared using the Clear button, the Text property is not updated.

Also, as a confirmation, the Xamarin.Forms PropertyChanged event is also not fired for the RadAutoComplete.Text Property 

Test 1 : Use the following repro for the Binding test:

<telerikInput:RadAutoComplete Text="{Binding SelectedInsurer, Mode=TwoWay}" />

public string SelectedInsurer
{
    get => selectedInsurer;
    set
    {
        SetProperty(ref selectedInsurer, value);
        // This is not hit on iOS when the Text is cleared using the "X" button
    }
}


Test 2 : Use this code for the PropertyChanged test:

AutoComplete.PropertyChanged += AutoComplete_PropertyChanged;

// Not executed on iOS when the Clear button is used.
private void AutoComplete_PropertyChanged(object sender, PropertyChangedEventArgs e)
{
    if (e.PropertyName == "Text")
    {
        Debugger.Break();
    }
}
