使用CodeIgniter调用控制器失败的AJAX

I've started my first CodeIgniter project and am having a lot of trouble making an Ajax call to my controller. I've put a simple echo statement in the controller but am getting a console error in the browser - POST http://localhost:8888/lotto/get_results/ 404 (Not Found). This leads me to believe that i'm not referencing the controller properly in the AJAX call. Below is the relevant code.

View - index.php

$(document).ready(function(){
    $('#notification').hide();
    retrieveValues();
});

$('.numDraws').change(function(){
    retrieveValues();
});

function retrieveValues() {
    if (!checkConnection()) {
        $('#notification').html("<span>No internet connection available</span>");
        $('#notification').slideDown(500, 'linear');
        return;
    } else {
        $('#notification').slideUp(500, 'linear');
        $('#loading').fadeIn(200);
        var numOfDraws = parseInt($('.numDraws').find('option:selected').val());
        if (isNaN(numOfDraws)) {
            numOfDraws = "ALL"; 
        }
        $.ajax({
            url: "/lotto/get_results/",
            type: "post",
            data: {numOfDraws:numOfDraws},
            success: function (data) {
                // var json = $.parseJSON(data);
                // setTimeout(function(){displayResults(json)} ,1200);
                alert(data);
            }
        }); 
    }

} 

Controller - lotto.php

<?php 

class Lotto extends CI_Controller {

    public function __construct()
    {
        parent::__construct();
        $this->load->model('lotto_model');
    }

    public function index()
    {
        $data['title'] = "Home";

        $this->load->view('templates/header', $data);
        $this->load->view('lotto/index');
        $this->load->view('templates/footer');

    }

    public function get_results($numOfDraws) {
        //$data['results'] = $this->lotto_model->get_results(1);
        echo "Reached the controller";
    }
}
?>

Also in my config file i've got the following:

$config['base_url'] = '';
$config['index_page'] = '';
$config['uri_protocol'] = 'AUTO';

Any help would be appreciated - i've spent a lot of time on this but can't seem to figure it out.
