Ninject - the request area has already been placed

I use Ninjectboth the EventBroker and DependencyCreation extensions in the MVC 3 application. I installed and use the Ninject.MVC3 package and therefore OnePerRequestModule.

I am trying to enter a service called IParentServicein a controller. IParentServicehas a dependency ChildServicecreated using the DependencyCreation extension (without a hard link).

Both services are registered in the local instance of the event broker (locally for ParentService).

I want to IParentServicebe covered for each request, and I want the dependency and event broker to be deleted at the same time as IParentServiceI am, however ScopeDisposedException. What am I doing wrong?

Some codes:

Service Definitions:

public interface IParentService
{
}

public class ParentService : IParentService
{
    [EventPublication("topic://ParentService/MyEvent")]
    public event EventHandler<EventArgs> MyEvent;
}

public class ChildService
{
    [EventSubscription("topic://ParentService/MyEvent", typeof(bbv.Common.EventBroker.Handlers.Publisher))]
    public void OnMyEvent(object sender, EventArgs eventArgs)
    {            
    }
}

Kernel Registration (NinjectWebCommon)

    private static void RegisterServices(IKernel kernel)
    {
        kernel.Bind<IParentService>().To<ParentService>()
            .InRequestScope()
            .OwnsEventBroker("ParentServiceBroker")
            .RegisterOnEventBroker("ParentServiceBroker");

        kernel.DefineDependency<IParentService, ChildService>();
        kernel.Bind<ChildService>().ToSelf()
            .WhenInjectedInto<ParentService>()
            .InDependencyCreatorScope()
            .RegisterOnEventBroker("ParentServiceBroker");            
    }
