Change Password Plugin

Hi,
    i wanted to replace nopcommerce change password process so i created a plugin in v2.4

I also created a RouteProvider.cs file in this plugin where i wrote

RouteTable.Routes.Remove(RouteTable.Routes["Register"]); //remove the existing register process

routes.MapRoute("Register", "register/",
                                                         new { controller = "ChangePassword", action = "Index" },
                                                         new[] { "Nop.Plugin.CustomerManager.Controllers" }

but now when i try to access the /register url it gives me page not found error.

I have installed the plugin, but nothing works. please help.
