jquery - Web API Controller not found on PUT -

i having trouble finding put action of web api 2 controller. i'm using mvc5. action in controller found , working when called. have tried several different ways of hitting this, no avail. appreciate hints.

the jquery call:

 var data = {         id: 1,         text: 'test'     };  var jsondata = json.stringify(data); $.ajax({     url: serviceroot  + "approval/" +  id,     type: 'put',     contenttype: "application/json; charset=utf-8",     data: jsondata,     success: function (results) {         alert('content saved.');     } }) 

the request object used in controller:

public class contentrequest     {         public int id { get; set; }         public string text { get; set; }     } 

route startup:

routes.maproute(                 name: "default",                 url: "{controller}/{action}/{id}",                 defaults: new { controller = "home", action = "index", id = urlparameter.optional }             ); 

the controller:

using system.collections.generic; using system.web.http; using system.net; using system.net.http;  namespace seacretgarden.web.controllers {     public class approvalcontroller : apicontroller     {          [httpput]         public ihttpactionresult put(int id, contentrequest content)         {             return statuscode(httpstatuscode.nocontent);         }     } }
