Node.js hash updated password - node.js

Question

Well, i have simple user edit in node,express,mongodb. But i am unable to hash password to bcrypt. In registration works everything allright but that was tutorial...
Here is part of my routes/users.js
Everything is updated but password is not hashed and i dont know what to do.
router.post("/profile", function (req, res) {
let user = {};
user.firstname = req.body.firstname;
user.lastname = req.body.lastname;
user.email = req.body.email;
user.password = req.body.password;
user.password2 = req.body.password2;
req.checkBody("firstname", "Firstname is required").notEmpty();
req.checkBody("lastname", "Lastname is required").notEmpty();
req.checkBody("email", "Email is required").notEmpty();
req.checkBody("email", "Email is not valid").isEmail();
req.checkBody("password", "Password is required").notEmpty();
req
.checkBody("password", "Password must be longer then 8 chars bitch")
.len(8, 64);
req
.checkBody("password2", "Passwords do not match")
.equals(req.body.password);
var errors = req.validationErrors();
if (errors) {
res.render("profile", {
errors: errors
});
} else {
bcrypt.genSalt(10, function(err, salt) {
bcrypt.hash(user.password, salt, function(err, hash) {
user.password = hash;
});
});
let query = {_id:req.user.id}
User.update(query, user, function(err){
if(err){
console.log(err);
return;
} else {
res.redirect('/');
}
});
}});
Here is my hasing for registration in models/users.js that i was inspired by.
module.exports.createUser = function(newUser, callback) {
bcrypt.genSalt(10, function(err, salt) {
bcrypt.hash(newUser.password, salt, function(err, hash) {
newUser.password = hash;
newUser.save(callback);
});
});
};
I will be thankfull for any help.

Well after hous its solved.
I just changed it to.
bcrypt.genSalt(10, function(err, salt) {
bcrypt.hash(user.password, salt, function(err, hash) {
user.password = hash;
let query = {_id:req.user.id}
User.update(query, user, function(err){
if(err){
console.log(err);
return;
} else {
res.redirect('/');
}
});
});
});
}});
