Refreshing the data fetched by Osmosis

Hi,

I am trying to use Osmosis to fetch data from a website. I made a button that calls a function where I set the osmosis scope. My issue is that when I click on the button for the first time, the data is fetched from the site, but if I click again on the button, I still get the same data even tough the data has changed on the website. Here's a snippet of my code:

import UIKit
import Osmosis

class ViewController: UIViewController {

    @IBOutlet weak var quote: UILabel!

    var array: [[String: AnyObject]] = []

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        self.quote.text = "This is my initial text."

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func getQuotes() {

        var updateText: String = ""

        Osmosis(errorHandler: { (error) -> Void in
            print(error)
        })
            .get(NSURL(string: "http://www.excemple.com")!)
            .find(OsmosisSelector(selector: ".wrapper"), type: .CSS)
            .populate([
                OsmosisPopulateKey.Single("div") : OsmosisSelector(selector: ".div")
                ], type: .CSS)
            .list { (dict) -> Void in
                self.array.append(dict)

                // Cast self.array[0] to String
                updateText = self.array[0]["div"] as! String

                // Truncate the string to remove unwanted \n \t
                updateText.removeAtIndex(updateText.startIndex)
                updateText.removeAtIndex(updateText.startIndex)
                updateText.removeAtIndex(updateText.endIndex.predecessor())

                print(updateText)
                //Update UI by the main thread (to avoid slow display update)
                dispatch_async(dispatch_get_main_queue()) {
                    self.quote.text = updateText
                }
            }
            .start()
    }

    @IBAction func refreshButton(sender: AnyObject) {

        getQuotes()
}

How can I refresh my data fetch by Osmosis ?
