How do you clear all data in express session without stopping it?

I write a code something like this

var express = require('express');
var app = express();
var session = require('express-session');
var cookieParser = require('cookie-parser');
app.use(session({ secret: makerandstr() }))
//                                        ^^^^^^^^^^^^^^^ this function generate random string
//other node.js setting including fs, body-parser

app.post('/api/v1/login', function(req, res) {
    var users = readdata("users");
    var sess = req.session;
    if (users[req.body.username]) {
        if (users[req.body.username].pwd == req.body.password) {
            sess.login = true;
            sess.username = req.body.username;
            sess.role = users[req.body.username].role;
            res.redirect(302, '/testsess');
    } else {
        sess.login = false;
        sess.loginerror = "User authorize failed";
        res.redirect(302, '/login')

With the above code I tried to clear the data of previous session using req.session.destroy(); function but it seems like you can't store data after you destroy it.

So how can I clear the data in the session and can store data right after it?
