created_at and updated_at not working

[netoolii]

I added this code in my project:

var orm = require("orm");
var modts = require('orm-timestamps');
orm.settings.set("instance.returnAllErrors", true);
orm.settings.set("connection.reconnect", true);
orm.settings.set("connection.pool", true);
orm.settings.set("connection.debug", true);
orm.connect("mysql://root:@localhost/laser_control", function (err, db) {
	if (err) throw err;	
           db.use(modts);

           var user = db.define("users", {
			id			: {type: 'serial'},
			name		: { type: 'text', required : true},
			mail		: { type: 'text', unique: true, required : true},
			password	: { type: 'text', required : true},
			crm			: { type: 'integer', key: true },
			city		: { type: 'text', key: true, size: 2},
			id_socket	: { type: 'text', size: 100},
			status		: { type: "enum", values: [ "1", "0"], defaultValue: "1" },
		}, {
			timestamp: true
		});

	db.sync(function(err) {
		if (err) throw err;
	});
});

it create all my model including created_at and updated_at, but everytime that i insert a new user, my fields created_at and updated_at keep the value "NULL" in database, i'm doing something wrong ?

obs: my code isn't give any error, it just not fill with the values that i want.
