Reload the page in Node.js using Express and EJS

I'm trying to reload the browser page when the underlying data model changes:

var request = require('request');
var express = require('express');
var app = express();
var bodyParser = require('body-parser');

app.set('view engine', 'ejs');
app.use(bodyParser.urlencoded({ extended: false }));

var requests;

app.get('/', function(req, res) {
    res.render('index', {
        requests: requests
    });
});

app.listen(3000);

...and later when requests data model changes:

request.get('localhost:3000/', function(error, response, body) {
    console.log(body);
});

but my browser page doesn't refresh unless I manually tap the refresh button with my mouse. What am I missing?

EDIT: Here is my index.ejs code:

<!DOCTYPE html>
<html>

<ul>
    <% requests.forEach(function(match) { %>
        <form action="/acceptRequest" method="post" enctype="application/x-www-form-urlencoded">
            <input type="text" name="id" value="<%= match.id %>">
            <input type="text" name="fighter1" value="<%= match.fighter1 %>"> vs.
            <input type="text" name="fighter2" value="<%= match.fighter2 %>"> on
            <input type="text" name="fightdate" value="<%= match.date %>"> in
            <input type="text" name="rounds" value="">
            <input type="submit" value="Submit">
        </form>
        <br>
        <% }); %>
</ul>

</html>


To reload the html page:

<script>
location.reload(true/false);
</script>

Also, you want to restart the server whenever a change is made use nodemon instead of nodejs to run your server.

To install nodemon:

npm install -g nodemon

To run the server(app.js is the main server file)

nodemon apps.js

Nodemon looks for the changes and restarts the server whenever found.
