node.js - mongoose - while sending a data from client to server with ajax-post request

1question.txt

Hi,

I'm trying to send a mongodb schema from client to the server. I put the server (server.js) and client (client.js) codes above. When I press the button on the client side, I log the incoming data into the console. 

In the console output what I have is:

{
field1: `container field`,
subSchema: []
}

However, what I expect to have is:

{
field1: `myfield`,
subSchema: { field1:`sub field1`, field2: `sub field2` }
}

Why can't I get the exptected result? Do you have any comment?

Thanks in regard...

2client.js

var subSchema1 = {
field1: "sub field1",
field2: "sub field2"
};

var container1  = { 
field1: "container field",
subSchema: subSchema1
}; 

$(document).ready(function() {
    $('button').button();

    $('button').click(function() {
        $.ajax({type: 'POST',
            url: "/send",
            data: container1,             // here I send the data when the button on the browser is clicked.
            dataType: "json"
        }).done(function( msg ) {
            console.log( "Data Saved: " + msg );
        }).fail(function(msg){
            console.log("Fail! " +msg.data);
        });
    });
});

3server.js

//create express web framework
var express = require('express');
var app = express();
var util = require('util');
app.use(express.static(process.cwd() + "/public"));
app.use(express.bodyParser());
app.listen(9000);

var mongoose = require('mongoose');
var db = mongoose.createConnection('localhost', 'deneme');

var subfieldSchema = mongoose.Schema({
    field1: 'string',
    field2: 'string'
});
var subfieldSch = db.model('subfieldSchema', subfieldSchema);

var containerSchema = mongoose.Schema({
    field1: 'string',
    subSchema: [subSchema]
});
var containerSch = db.model('tag', tagSchema);

app.post('/send', function(req,res){
    if (req.body ){
        var newVal = new Route({
            field1: req.body.field1,
            subSchema: req.body.subSchema
        });

        util.log(newVal);
        newVal.save(function(err){
            res.end("Err: Send ended!");
        });
        res.send({status: "ok", message: "Received."});
    }else{
        res.send({status: "nok", message: "Nothing received."});
    }
});
