I would recommend you using the ~/App_Start/NinjectMVC3.cs file to configure the Ninject kernel:

[assembly: WebActivator.PreApplicationStartMethod(typeof(AppName.App_Start.NinjectMVC3), "Start")]
[assembly: WebActivator.ApplicationShutdownMethodAttribute(typeof(AppName.App_Start.NinjectMVC3), "Stop")]

namespace AppName.App_Start
{
    using System.Web.Mvc;
    using Microsoft.Web.Infrastructure.DynamicModuleHelper;
    using Ninject;
    using Ninject.Web.Mvc;
    using Ninject.Web.Mvc.FilterBindingSyntax;

    public static class NinjectMVC3
    {
        private static readonly Bootstrapper bootstrapper = new Bootstrapper();

        /// <summary>
        /// Starts the application
        /// </summary>
        public static void Start()
        {
            DynamicModuleUtility.RegisterModule(typeof(OnePerRequestModule));
            bootstrapper.Initialize(CreateKernel);
        }

        /// <summary>
        /// Stops the application.
        /// </summary>
        public static void Stop()
        {
            bootstrapper.ShutDown();
        }

        /// <summary>
        /// Creates the kernel that will manage your application.
        /// </summary>
        /// <returns>The created kernel.</returns>
        private static IKernel CreateKernel()
        {
            var kernel = new StandardKernel();
            RegisterServices(kernel);
            return kernel;
        }


        /// <summary>
        /// Load your modules or register your services here!
        /// </summary>
        /// <param name="kernel">The kernel.</param>
        private static void RegisterServices(IKernel kernel)
        {
            kernel.Bind<DataContext>().ToSelf().InRequestScope();
            kernel.Bind<IWikiRepository>().To<WikiRepository>();
            kernel.Bind<IWikiService>().To<WikiService>();
            kernel.BindFilter<WikiFilter>(FilterScope.Global, 0);
        }
    }
}

and the Global.asax stays unchanged. By the way that's the default setup when you install the Ninject.MVC3 NuGet package.
