WPF:按钮控制模板不触发点击事件

我正在制作我自己的服装按钮，其中有一个标签。出于某种原因，我的按钮没有对"点击"事件做出反应，点击功能也没有发挥作用。为什么?

这是我的按钮样式xaml代码:

   <Style x:Key="MyMenuButtonStyle" TargetType="{x:Type Button}">
        <Setter Property="Background" Value="#AF4EB4EC"/>
        <Setter Property="Foreground"  Value="White"/>
        <Setter Property="BorderThickness" Value="0"/>
        <Setter Property="Margin" Value="0,0,5,0"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Button}">
                    <Grid >
                        <Rectangle Fill="{TemplateBinding Background}"  StrokeThickness="0" MinWidth="{Binding ElementName=lblCnt,Path=Width}"/>
                        <Label Name="lblCnt" Content="{TemplateBinding Content}"  HorizontalAlignment="Center" VerticalAlignment="Center" 
                               Foreground="{TemplateBinding Foreground}" FontSize="{TemplateBinding FontSize}" Background="{TemplateBinding Background}"
                               Height="auto" Width="auto"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
        <Style.Triggers>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter Property="Cursor" Value="Hand"/>
                <Setter Property="Background" Value="White"/>
            </Trigger>
            <EventTrigger RoutedEvent="UIElement.MouseEnter">
