IBAction not work with scrollview

Hi, I'm using NSSplitViewController and once I load a viewcontroller with scrollview the IBActions of NSSwitch,NSButtons etc not work after I added the scrollview How can I fix it?

import Foundation
//Categories Protocal delegate
protocol CategoriesViewControllerDelegate: AnyObject {
    func didSelectCategory(category: String)
}

class DetailViewController:NSViewController, NSOutlineViewDataSource, CategoriesViewControllerDelegate {
    weak var delegate: CategoriesViewControllerDelegate?

    override func viewDidLoad() {
        // Other setup code...
        detViewController = self
        loadViewControllerWithScrollView(GeneralSettingsViewController.self, storyboardIdentifier: "GeneralSettingsViewController", originalViewController: self)
    }
    
    func didSelectCategory(category: String) {
           // Handle the selected category in DetailViewController
           print("Selected category: \(category)")

           // Load the corresponding view controller or perform any other actions
           switch category {
           case "General":
               // Load GeneralSettingsViewController
               // Example: self.replaceCurrentViewController(with: GeneralSettingsViewController())
               print("Load GeneralSettingsViewController")
               loadViewControllerWithScrollView(GeneralSettingsViewController.self, storyboardIdentifier: "GeneralSettingsViewController", originalViewController: self)
           case "DynaMusiX":
               // Load DynaMusicSettingsViewController
               // Example: self.replaceCurrentViewController(with: DynaMusicSettingsViewController())
               print("Load DynaMusicSettingsViewController")
               loadViewControllerWithScrollView(DynaMusicSettingsViewController.self, storyboardIdentifier: "DynaMusicSettingsViewController", originalViewController: self)
           case "DynaGlance":
               // Load DynaGlanceSettingsViewController
               // Example: self.replaceCurrentViewController(with: DynaGlanceSettingsViewController())
               print("Load DynaGlanceSettingsViewController")
               loadViewControllerWithScrollView(DynaGlanceSettingsViewController.self, storyboardIdentifier: "DynaGlanceSettingsViewController", originalViewController: self)
               
           default:
               break
           }
       }
}
 
//Load viewcontroller with scrollview
func loadViewControllerWithScrollView<T: NSViewController>(_ viewControllerType: T.Type, storyboardIdentifier: String, originalViewController: NSViewController) {
    let storyboard = NSStoryboard(name: NSStoryboard.Name("Main"), bundle: nil)
    let newViewController = storyboard.instantiateController(withIdentifier: NSStoryboard.SceneIdentifier(storyboardIdentifier)) as! T

    // Remove existing child view controllers
    for childVC in originalViewController.children {
        childVC.removeFromParent()
        childVC.view.removeFromSuperview()
    }

    // Wrap the new view controller's view in a scroll view
    let scrollView = NSScrollView()
    scrollView.documentView = newViewController.view
    scrollView.autoresizingMask = [.width, .height]
    scrollView.hasVerticalScroller = true
    scrollView.hasHorizontalScroller = false
    scrollView.contentView.scroll(to: NSPoint(x: 0, y: newViewController.view.frame.height))
    scrollView.translatesAutoresizingMaskIntoConstraints = true

    // Set user interaction for the content view inside the scroll view
    scrollView.documentView?.translatesAutoresizingMaskIntoConstraints = true
    scrollView.documentView?.needsLayout = true

    // Add the scroll view as a subview of the original view controller
    originalViewController.view.addSubview(scrollView)
    scrollView.frame = originalViewController.view.bounds
    scrollView.layer?.zPosition = -1
}
