WPF - IsEnabled DependencyProperty binding not working properly

Question

I have a dependency property defined in my window as shown below:

public static readonly DependencyProperty IsGenericUserProperty = DependencyProperty.Register("IsGenericUser", typeof (bool), typeof (MainWindow));
public bool IsGenericUser
{
    get { return (bool) GetValue(IsGenericUserProperty); }
    set { SetValue(IsGenericUserProperty, value); }
}

In my window constructor, I set the data context of the container holding the button:

QuickListButtonsStackPanel.DataContext = this;

I bind the dependency property to the IsEnabled property of the button:

<Button IsEnabled="{Binding IsGenericUser}" .../>

When started, IsGenericUser is true, so the button is turned on. When I set IsGenericUser to false, the button is disabled. However, if I go back to IsGenericUser again, nothing happens to the button and it remains disabled. What am I doing wrong?

Thanks!

edit: Here is the style that I use with the button. This style causes a problem (if the button does not have a custom style, it works fine):

<Style x:Key="BlackButtonStyle" TargetType="{x:Type Button}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
