uwp checkbox double Tapped

When uwp sets the Tapped event on the parent grid, the child checkbox is automatically checked to be double Tapped.

I want to check the child checkbox as Tapped instead of double Tapped.

Thank you for your reply.

<Grid Background="Black" >
    <interactivity:Interaction.Behaviors>
    <core:EventTriggerBehavior EventName="Tapped">
        <core:InvokeCommandAction Command="{Binding DataContext.SelectDefectImageCommand, ElementName=PART_ItemList}" CommandParameter="{Binding}" />
    </core:EventTriggerBehavior>
    </interactivity:Interaction.Behaviors>

    <CheckBox IsChecked="{Binding IsSelected, Mode=TwoWay}" Style="{StaticResource WhiteCheckBoxStyle}" VerticalAlignment="Center" Margin="5,0,0,0" />

</Grid>
