Express.js - Posted data not rendering until refresh the page - node.js

Question

I am send and fetch data from MySql Database with Express.js and Sequelize.js. All my code works correctly. My problem is, posted data not rendering on the Handlebars template until refresh the page. I also tried res.render method after SaveSettings method but don't worked. I want to render updated data after redirect.
Solved
You're missing return before settings.update(). Without it, the SaveSettings promise resolves before the update has completed - #Phil
function SaveSettings(Model, values) {
return Model.findByPk(1).then((settings) => {
if (!settings) {
return Model.create(values).catch((e) => console.log(e));
} else {
return settings.update(values).catch((e) => console.log(e));
}
});
}
Routes
router.get("/admin", csrf, isAuth, controller.getGeneral);
router.post("/admin", isAuth, controller.postGeneral);
Controllers
exports.getGeneral = (req, res) => {
Models.General.findByPk(1).then((result) => {
return res.render("dashboard/index", {
title: "General Settings",
data: result,
});
});
};
exports.postGeneral = (req, res) => {
SaveSettings(Models.General, req.body)
.then(() => res.redirect("/admin"));
};
SaveSettings Method
function SaveSettings(Model, values) {
return Model.findByPk(1).then((settings) => {
if (!settings) {
return Model.create(values).catch((e) => console.log(e));
} else {
settings.update(values).catch((e) => console.log(e));
}
});
}
