Vim tab spacing after enter (new line)

Question

I've this tab spacing configuration:

set autoindent
set smartindent
set expandtab tabstop=4 shiftwidth=4 smarttab softtabstop=4

and at the end of configuration, I put this:

autocmd FileType javascript,jade,json set shiftwidth=2 tabstop=2 softtabstop=2

The 2 spaces tab works just fine. But, if I type enter (new line), it became 4 spaces. Here is the example:

     var Post = orm.define('Post', {       
       title: sequelize.STRING,      
       content: sequelize.STRING,
         | /* wrong spaces */
     });

But if I use 4 tab spaces, it also use 4 spaces after enter.

I can't figure out what's the problem.

EDIT:

It ONLY happened when I write object-literal in a javascript callback function (like the code example above). It works fine with general code statement and in json object-literal. Here is the example:

    /* the 2 spaces works fine*/
    app.set('port', 3000);
    app.use(express.bodyParser());

    /* also works fine here */
    var config = {
      host: 'localhost',
      port: 5432
    }
