MVC4

Hi,
I have a web api controller and a knockout.js page for my js files. i need two post methods in my api controller. Now my code is this:

In knockout.js

self.addTicket = function () {
        $.ajax({
            url: "api/helpdeskapi/Post",
            type: 'post',
            data: ko.toJSON(this),
            contentType: 'application/json',
            success: function (result) { }
        });
        $('#AddNewTicketpopup').dialog('close')

self.addCategory = function () {
            $.ajax({
                url: "api/helpdeskapi/AddCategory",
                type: 'post',
                data: ko.toJSON(this),
                contentType: 'application/json',
                success: function (result) { }
            });

In api controller:

public HttpResponseMessage Post(TKTJOB job)
       {
           HelpDeskRepository.AddJob(job);
           var response = Request.CreateResponse<TKTJOB>(HttpStatusCode.Created, job);
           string uri = Url.Link("DefaultApi", new { id = job.JobId });
           return response;
       }

public HttpResponseMessage AddCategory(JOBCATEGORY category)
        {
            HelpDeskRepository.AddCategory(category);
            var response = Request.CreateResponse<JOBCATEGORY>(HttpStatusCode.Created, category);
            string uri = Url.Link("DefaultApi", new { id = category.CategoryId });
            return response;
        }

when i run this i can post only the ticket values(that is only the first post method is working). Second one is not working.


Can anyone help me in doing this.
