moveToPage implementation incorrect

`class FeaturedSwipeViewController: EZSwipeController, UIGestureRecognizerDelegate {

let seg = UISegmentedControl(items: ["1", "2"])

var advisor: Advisor!

override func setupView() {
    super.setupView()
    datasource = self
    navigationBarShouldNotExist = true

override func viewDidLoad() {
    super.viewDidLoad()
    seg.selectedSegmentIndex = 0
    seg.frame = CGRect(x: 0, y: 0, width: 200, height: 30)
    seg.addTarget(self, action: #selector(switchViewController(sender:)), for: .valueChanged)
    self.navigationItem.titleView = seg 
}

    get {
        return navigationController?.topViewController != self

extension FeaturedSwipeViewController: EZSwipeControllerDataSource {
func viewControllerData() -> [UIViewController] {

    let featuredTopicVC = STORY_BOARD.instantiateViewController(withIdentifier: "featuredTopicVC") as! FeaturedTopicTableViewController
    
    let featuredAMAVC = FeaturedAMATableViewController()
    
    return [featuredTopicVC, featuredAMAVC]

func changedToPageIndex(_ index: Int) {
    seg.selectedSegmentIndex = index
}

}

When tap on the second item of segmentedControl EZSwipeVC can move to second page correctly, but after sequentially tapping on the first segmentedControl item EZSwipeVC can't move back to the first page. Sorry for the broken code block styling.
