jquery - Trouble With C# MVC Ajax request -

so having trouble calling function in c# controller. whenever ajax request made, controller automatically redirects main view of controller, "index" method. if put breakpoint, function never reaches function "favorite", , instead redirects. i've been @ while, , don't see i'm doing wrong. thanks.

here ajax function:

    var updatefavorites = function (event) {         $.ajax({             type: 'post',             url: baseurl + '/post/favorite',             data: {                 id: $(this).attr('data-id'),                 isfavorite: $(this).attr('data-favorite')             },             success: function () { },             complete: function () { }         });         event.preventdefault(); 

here favorite method:

    [system.web.mvc.httppost]     public jsonresult favorite(int id, bool isfavorite)     {         "code here..."     } 

here default view:

    public actionresult index()     {          "code here..."     } 

does have idea happening? i've been staring @ code , trying different things hours can't seem find bug. thanks!

edit:

here things asked for:

routing config:

    routes.maproute("specificpost", "post/{title}/{action}",             new { controller = "post", action = "details", },             new { title = @".*" });      routes.maproute("create", "post/{action}",             new { controller = "post", action = "create", });          // mvc default     routes.maproute("default", "{controller}/{action}", new { controller = "post", action =   "index" }); 

html(this button, not sure else want):

    <span class ="btn favoritebutton" data-id="@model.id" data-favorite="@model.isfavorite">favorite</span> 

also jquery:

    $('.favoritebutton').click(updatefavorites); 

it looks me following route definition redirect ../post/create route matching "post/{anything}"

routes.maproute("create", "post/{action}",     new { controller = "post", action = "create", }); 

you remove route definition and, long request comes in http 'post', default route:

routes.maproute("default", "{controller}/{action}", new { controller = "post", action =   "index" }); 

will correctly route "post/favorite" postcontroller.favorite() action.
