json - Passing model from view to vontroller via Jquery ajax -

i'm trying pass json data view controller reason not wanting work. when debug controller, model showing null , life of me cannot figure out why.

here's controller:

        public jsonresult updatevideourl(list<geturldata> model)     {         //var updateurls = new appservices.video.updateallvideo();         //var loginvideourl = model.tostring();         //dynamic update = updateurls.execute(model);         return json(model);     } 

my view:

    $('#btnupdate').click(function (e) {     //debugger;     var model = {         'model.loginfiles.englishvideourl': $("#loginenvideoinput").val(),         'model.loginfiles.spanishvideourl': $("#loginesvideoinput").val(),         'model.welcomefiles.englishvideourl': $("#welcomeenvideoinput").val(),         'model.welcomefiles.spanishvideourl': $("#welcomeesvideoinput").val(),         'model.benefitfiles.englishvideourl': $("#benefitenvideoinput").val(),         'model.benefitfiles.englishvideourl': $("#benefitesvideoinput").val(),         'model.myenrollmentfiles.englishvideourl': $("#myenrollmentenvideoinput").val(),         'model.myenrollmentfiles.englishvideourl': $("#myenrollmentesvideoinput").val(),         'model.adminsidefiles.englishvideourl': $("#adminsideenvideoinput").val(),         'model.adminsidefiles.englishvideourl': $("#adminsideesvideoinput").val()     }     $.ajax({         type: "post",         url: '@url.action("updatevideourl", "managevideos")',         data: json.stringify(model),         contenttype: 'application/json; charset=utf-8',         //async: true,         success: function (model) {             //return model         },         error: function (jqxhr, errorthrown, errorthrown) {             console.log("there error on post: " + " " + errorthrown + "." + "  please see above if applicable");         }     }); }); 

and model:

    public class applicationvideomodel {     public list<geturldata> geturldata { get; set; } }  public class geturldata {     public geturldata(string englishurl, string spanishurl)     {         englishvideourl = englishurl;         spanishvideourl = spanishurl;     }     public string englishvideourl     {         get;         set;     }     public string spanishvideourl     {         get;         set;     } } 

what overlooking here?

model comes null because convert one object , not list of objects.

if change parameter in post method to:

public jsonresult updatevideourl(geturldata model) {     return json(model); } 

then model won't null.

if need send list parameter, have stringify array of objects this:

var model = [{     'model.loginfiles.englishvideourl': $("#loginenvideoinput").val(),     next properties             },             {     second object             }]
