Have working javascript function, need to add it into an alexa function on lambda [on hold]

I have loaded the modules using npm, and I have the following code snippet

var request = require('request');
var cheerio = require('cheerio');
var url = "https://www.google.com/search?q=current+date";

request(url, function(error, response, body) {
  if(!error) {
    console.log("Status code: " + response.statusCode);
    var $ = cheerio.load(body);
    date = $("div > div > div > div > span").text().trim();
    console.log("Date: " + date);
  } else {
     console.log("Error: " + error);
  }
});

I want to call a function that does the same thing from amazon's alexa, I tried:

'GetDate': function(){
    //this.emit(':tell', 'activated');

    var url = "https://www.google.com/search?q=current+date";
    request(url, function(error, response, body) {
        if(!error) {
            //var $ = cheerio.load(body);
            //var date = $("div > div > div > div > span").text().trim();
            //this.emit(':tell', 'Date: ' + date);
    this.emit(':tell', 'activated1');
        } else {
            //this.emit(':tell', 'Error connecting');
    this.emit(':tell', 'activated2');
        }
     });

},

But it's producing an error and I cannot tell why. Any ideas?
