Unable to send json data using durandal JS using Knockout Binding

var   xyz=  { 
              a: ko.observable(),
              b: ko.observable(),
              c: ko.observable(),   
              d: ko.observable()

           };
        function setupControlEvents()
    {
        $("#save").on("click",handleSave);                    
    }

    function handleSave()
    {

        var data = ko.toJSON(xyz);
        //alert("data to send "+data);
        //var d = serializer.serialize(data);
        url ="../save";
    http.post(url,data).then(function(){
            alert("success");
            console("save was success");
         });

I am able to get the data but unable to save .. when i alert the data that i am sending i get this data to send {"a":"A","b":"B","c":"C","d":"D","observable":{"full":true}}

i tried to serialize with durandal's serialize.serialize() but still not working .. i think i am unable to send the data because i am getting obserbvable in json data so please kindly help me to solve this..

You are applying ko.toJSON() twice. The method post from the http plugin in Durandal is already doing it. Take a look at the method code:

post:function(url, data) {
        return $.ajax({
            url: url,
            data: ko.toJSON(data),
            type: 'POST',
            contentType: 'application/json',
            dataType: 'json'
        });
    }

So you only need to do this:

url ="../save";
http.post(url,xyz).then(function(){
        alert("success");
        console("save was success");
});
