I wrote a script with node.js and why is there no change?

If you run, there is no change.
Where is the problem? For reference, NPM installed Cheerio and Express.

var express = require('express');
var request = require('request');
var cheerio = require('cheerio');
var router = express.Router();

var numOfMovies = 50;
var parsedResults = new Array();

/* GET home page. */
router.get( '/', function( req, res ) {

request('http://movie.naver.com/movie/running/current.nhn?order=reserve',
function ( error, response, html ) {

  if ( !error && response.statusCode == 200 ) {
    var $ = cheerio.load( html );

    parsedResults = [];

    var cnt = 0;

    $('dt.tit').each( function ( i, element ) {

      if ( cnt < numOfMovies ) {
        var movie_list = $(this);
        var movie_title = movie_list.children().eq(1).text();

        var star = movie_list.next();
        var infoStar = star.children().eq(0);
        var dd = infoStar.children().eq(1);
        var star_t1 = dd.children().eq(0);
        var a_href = star_t1.children().eq(0);
        var num = a_href.children().eq(1);

        var movie_rating = num.text();

        // Our parsed meta data object
        var metadata = {
          movieTitle: movie_title,
          movieRating: movie_rating
        };

        // Push meta-data into parsedResults array
        parsedResults.push( metadata );
      }

      cnt++;
    });

    res.render( 'movie', {
      title: 'Movie Page Web Scraping',
      metadata: parsedResults
    } );

  }

});

} );

module.exports = router;
