NamedScopes Ninject and async bindings (threading)

My project is structured by services and repositories (all repositories share the db context). In one of my service levels, I have an asynchronous method that writes to the database using the repository. The web request will complete and delete the context before this method can use it. I tried to understand NamedScopes as indicated in this. I still do not understand how to implement this. I will show how my project is structured and hope someone can help me at the code level.

Handcuffs

    private static void RegisterServices(IKernel kernel)
    {
        //dbcontext
        kernel.Bind<EntityDatabaseContext>().ToMethod(context => new EntityDatabaseContext()).InRequestScope();

        //unit of work
        kernel.Bind<IUnitOfWork>().To<UnitOfWork>().InRequestScope();

        //repositories
        kernel.Bind<IRepository<Account>>().To<Repository<Account>>().InRequestScope();

        //services
        kernel.Bind<IAuthenticationService>().To<AuthenticationService>().InRequestScope();
    }

Authentication Service uses constructor injection

public AuthenticationService(UnitOfWork unitOfWork, IRepository<Account> accountRepository){}

Method inside my AuthenticationService

    //this is a background process
    public Task SomeMethodAsync(string text)
    {
        //spin it off into a new task
        return Task.Factory.StartNew(() => SomeMethod(text));
    }
