How to add events to templated control in silverlight?

Bounty Rewarded for any solid tutorial/learning resources regarding wiring up events with templated controls.

I Have a control template like this:

<Style TargetType="local:DatePicker">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="local:DatePicker">
                <Border Background="{TemplateBinding Background}"
                        BorderBrush="{TemplateBinding BorderBrush}"
                        BorderThickness="{TemplateBinding BorderThickness}" x:Name="myDatePickerContentArea">
                    <StackPanel Orientation="Vertical">
                        <Button x:Name="myTestButton" Content="Test button"  />
                        <telerik:RadDatePicker Style="{StaticResource VisitsReportTextBoxStyle}" Foreground="#FFFFFF"  x:Name="startDate" DateTimeWatermarkContent="Start Date"/>
                        <telerik:RadDatePicker Style="{StaticResource VisitsReportTextBoxStyle}"  x:Name="endDate" DateTimeWatermarkContent="End Date"/>
                    </StackPanel>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

The C# for this template is:

public class DatePicker : Control 
{

    public static readonly DependencyProperty StartDateSelectedDateProperty = DependencyProperty.Register("StartDateSelectedDateProperty", typeof(DateTime), typeof(DatePicker), null);
    public DateTime? StartDateSelectedDate { get; set; }


    public DatePicker()
    {
        this.DefaultStyleKey = typeof(DatePicker);            

    }



    public override void OnApplyTemplate()
    {
        RadDatePicker StartDate = this.GetTemplateChild("startDate") as RadDatePicker;
        StartDate.SelectionChanged += new Telerik.Windows.Controls.SelectionChangedEventHandler(StartDate_SelectionChanged);
        StartDate.SelectedDate = new DateTime(2010, 01, 01);            
        base.OnApplyTemplate();          
    }

    void StartDate_SelectionChanged(object sender, Telerik.Windows.Controls.SelectionChangedEventArgs e)
    {
        RadDatePicker temp = (RadDatePicker)sender;
        StartDateSelectedDate = temp.SelectedDate;
    }


}

My selectionChanged Event Doesn't Fire and I'm not sure why. Any Ideas ?
