Server to client messages not going through with SignalR in ASP.NET MVC 4

I created a simple test app to reproduce a problem I'm having in my main app. I have the following hub class: ``` [HubName("testHub")] public class TestHub : Hub { public TestHub() { System.Diagnostics.Debug.WriteLine("TestHub instantiated"); } public void RunMe() { System.Diagnostics.Debug.WriteLine("Client Started"); } public static void Notify(string msg) { var hubContext = GlobalHost.ConnectionManager.GetHubContext<TestHub>(); hubContext.Clients.All.notify("Hello!"); } } ``` My test web page is: ``` <form action="javascript: void(0)" method="post"> <input type="button" value="Do It!" onclick="hitHub()"/> </form> <div id="error"></div> <script type="text/javascript"> var tHub; $(document).ready(function () { tHub = $.connection.testHub; tHub.notify = function (msg) { alert(msg); } $.connection.hub.start().done(function () { tHub.server.runMe(); }); }); function hitHub() { $.ajax({ type: "POST", url: "@Url.Content("~/Hub/Test")" , success: function (data, textStatus, jqXHR) { }, error: function (data, textStatus, jqXHR) { $("#error")[0].innerHTML = data.responseText; alert("Error notifying hub."); } }); } </script> ``` And finally, my HubController: ``` public class HubController : Controller { [AcceptVerbs(HttpVerbs.Post)] public void Test() { TestHub.Notify("Got it!"); } } ``` In my Application_Start, I call RouteTable.Routes.MapHubs(); The hub gets instantiated. Then the call to runMe() gets passed to the server. This all works fine. Where it fails is when I click on the "Do It!" button. hitHub() gets called and my HubController.Test() method gets called. TestHub.Notify("Got it!") gets executed without any errors, however nothing happens on the client. What did I miss? Update 1: Based on answer from JcFx, changed the javascript above so that tHub.notify is set before calling $.connection.hub.start(). The problem remains, however. Update 2: What fiddler sees: Update 3: When I trace into the MessageBus.Publish() call, I notice tha the Topic has no subscriptions, so the topic never gets scheduled. I'm not sure how at what point I should be checking for the subscriptiont to be made...
