How to call a mixin action from view model?

[Paul Benedict Jabines]

If I have a View Model like this:

@DomainObject(
        nature = Nature.VIEW_MODEL
)
public class View {
    public Customer customer;

    public View(Customer customer) {
        this.customer = customer;
    }

    public void delete() {
        customer.delete();
    }
}

where customer.delete() is a mixin action. How to call it from the view
model?
