Express body parser

I have this code on the client side:

var dataObj={
        title:title
    };
    var dataJSON=JSON.stringify(dataObj);
    $.ajax({
        type:'POST',
        url:'/notebook/',
        data:dataJSON
    })
    .done(function(data){
        console.log("Notebook has been created");
    });

I have this code(using express bodyParser)

router.post('/',function(req,res){
    console.log(req.body);//
    console.log(req.body.title);
    /*var nb=new notebook({
        title:req.body.title,
        isActive:false
    });
    nb.save(function(err,doc){
        if(err)
            console.error(err);
        else
        {
            console.log("Notebook Document has been saved");
            console.log(doc);
        }
    });*/
});
