Dont load dll files to Ninject Kernel

I Use Ninject For DIP in My Mvc App and I work with it but I want to Load Some dll Files into My Ninject Kernel in ReportController with below code:

    private readonly IKernel _kernel;
    public ReportController(IKernel kernel)
    {
        _kernel = kernel;
    }

    public ActionResult Index()
    { 
     var directoryInfo = new DirectoryInfo(@"D:\Project\ReportDlls");
     var modules = directoryInfo.GetFiles("*.dll");
       foreach (var m in modules)
        {
            var assembly = Assembly.LoadFile(m.FullName);
            _kernel.Load(assembly);
        }

And I Read from kernel with below code but its return null routesProviders....Why??

       var routesProviders = _kernel.GetAll<IReport>();
            foreach (var rp in routesProviders)
            {
                if (rp.GetType().Name == "DailyResult")
                {
                    var f = rp.GetType();
                }
            }

My Interface is IReport and My Dll Derived from IReport and In class IocModule in my dll i wrote Kernel.Bind<IReport>().To<DailyResult>(); But Its Not work....???
