Mouse move over an item and an event be generated WPF

Question

I’m having difficulty implementing an effect where when I hover over the item on the screen the speed should be 0. And without the mouse above should be back to 30. Use WPF using MVVM structure, so events cannot be in the Class.xaml.Cs class I need an idea on the subject. Thank you!

<common:BrnN Grid.Row="1"
                                 ItemsSource="{Binding Items}"
                                 Speed="30"
                                 Background="Black">
                <common:BrnN.ItemTemplate>
                    <DataTemplate>
                        <Button Background="Transparent"
                                BorderThickness="0"
                                Margin="20, 0"
                                Padding="0"
                                Command="{Binding RelativeSource={RelativeSource AncestorType=common:BrN}, Path=DataContext.TagCommand}"
                                CommandParameter="{Binding}">

                            <StackPanel Orientation="Horizontal">
                                <TextBlock Text="{Binding Descricao}"
                                           Foreground="Gold"
                                           FontSize="18"
                                           FontWeight="Semibold" />
                                <TextBlock Text=": "
                                           Foreground="Gold"
                                           FontSize="18"
                                           FontWeight="Semibold" />
                                <TextBlock Text="{Binding Valor, StringFormat=F2}"
                                           Foreground="Gold"
                                           FontSize="18"
                                           FontWeight="Semibold" />

                            </StackPanel>
                        </Button>
                    </DataTemplate>
                </common:BrnN.ItemTemplate>

You can use events in the code associated with the element in question. I used a button with the name bt_teste to exemplify what I am saying and the following events.

    private void Bt_teste_MouseLeave(object sender, System.Windows.Input.MouseEventArgs e)
    {
        bt_teste.Content = "fora";
    }

    private void Bt_teste_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e)
    {
        bt_teste.Content = "sobre";
    }
