Customizing Group Header TItles

Hello - I am using a group descriptor to group items on an sfListView.  The Property that is being used is called "Checked", which brings in a 1 or 0 value.  So, with the group headers, the two groups are called 1 and 0.  I'd like to call them 'Failed' and 'Passed', respectively.  Is there a way to convert the property in the group headers to another value?

public class IntToStringConverter : IValueConverter  {    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)    {      if (value.ToString() == "1")        return "Passed";      return "Failed";    }      public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)    {      throw new NotImplementedException();    }  }

<DataTemplate x:Name="GroupHeaderTemplate"  x:Key="GroupHeaderTemplate">    <ViewCell>      <ViewCell.View>        <Grid BackgroundColor="#E4E4E4">          <Grid.ColumnDefinitions>            <ColumnDefinition Width="*" />          </Grid.ColumnDefinitions>            <Label Text="{Binding Key,Converter={StaticResource IntToStringConverter}}"                   FontSize="22"                   FontAttributes="Bold"                   VerticalOptions="Center"                   HorizontalOptions="Start"                   Margin="20,0,0,0" />        </Grid>      </ViewCell.View>    </ViewCell>  </DataTemplate>

Thanks for the response, Muthu!  This solution worked perfectly!
