How to use two schemas to create two collections in mongoose

Question

I'm storing some data I'm getting from API calls in a collection ('Asin'). - work just fine.

I build two pages -register & log in, installed all relevant bcrypt and saltRound modules.

But it seems that when I'm registering as a user, I'm not rendering to a "secret page" (in my case the homepage) and mongoose is not creating a new collection ('Users') in the mongo shell at all.

const mongoose = require('mongoose');
const bcrypt = require("bcrypt");
const saltRounds = 10;

const app = express();

app.set('view engine', 'ejs');
app.use(express.static("public"));
app.use(bodyParser.urlencoded({extended: true}));

mongoose.connect("mongodb://localhost:27017/asinDB", {useNewUrlParser: true, 
useUnifiedTopology: true});

const asinSchema = new mongoose.Schema ({
asinId:String,
parentAsinId:String,
categoryId:String,
feesId:Number,
buyBoxpriceId:Number
});

const userSchema = new mongoose.Schema({
email:String,
password:String
});

const Asin = mongoose.model("Asin", asinSchema);

const User = new mongoose.model("User",userSchema);
