Meteor.js adding more info on user account sign up

Question

Below is my code, but for some reason the first and last names aren't saved? How do I save additional info when creating a new user in Meteor? I'm using the accounts-password package.

Accounts.createUser({
  email: email,
  password : password,
  profile: {firstName: firstName, lastName: lastName}
}, function (err) {
  if (err) {
    // Inform the user that account creation failed
  } else {
    // Success. Account has been created and the user
    // has logged in successfully. 
  }
});

The onCreateUser callback should return the finall user object which is about to be saved into the database. The problem you have comes from the fact that the profile data need to be hooked manually tho the user object (see meteor docs for more details):

Accounts.onCreateUser(function(options, user) {
    // [...]
    if (options.profile)
        user.profile = options.profile;
    return user;
});
