NSTableView doesn't show new data

I have a NSTableView under a NSViewRepresentable and I'm trying to add a new row when the + button is clicked.
With the code below, the ForEach statement is updated when the data is added to the state variable, but the table view doesn't show the new element.

Why is that?

Code Block 
import PlaygroundSupport
import SwiftUI
struct TV: NSViewRepresentable {
  @Binding var students: Array<String>
   
  func makeNSView(context: Context) -> NSScrollView {
    let sv = NSScrollView()
    let tv = NSTableView()
    sv.documentView = tv
    tv.gridStyleMask = .solidHorizontalGridLineMask
    tv.usesAlternatingRowBackgroundColors = true//
    tv.allowsMultipleSelection = true
    let col = NSTableColumn(identifier: NSUserInterfaceItemIdentifier(rawValue: "Name"))
    col.title = "Name"
    _ = tv.addTableColumn(col)
     
    _ = tv.delegate = context.coordinator
    tv.dataSource = context.coordinator
    return sv
  }
  func updateNSView(_ nsView: NSScrollView, context: Context) {
    (nsView.documentView as! NSTableView).reloadData()
  }
  func makeCoordinator() -> Coordinator {
    Coordinator(self, students: self._students)
  }
     
  class Coordinator: NSObject, NSTableViewDelegate, NSTableViewDataSource {
    var parent: TV
    @Binding var students: Array<String>
    init(_ parent: TV, students: Binding<Array<String>>) {
      self.parent = parent
      self._students = students
    }
    func numberOfRows(in tableView: NSTableView) -> Int {
      return students.count
    }
    func tableView(_ tableView: NSTableView, objectValueFor tableColumn: NSTableColumn?, row: Int) -> Any? {
      print(students[row])
      return students[row]
    }
    func tableView(_ tableView: NSTableView, shouldEdit tableColumn: NSTableColumn?, row: Int) -> Bool {
      return true
    }
    func tableView(_ tableView: NSTableView, setObjectValue object: Any?, for tableColumn: NSTableColumn?, row: Int) {
      self.students[row] = object as! String
    }
  }
}
struct view: View {
  @State var students = ["John", "Mary", "Bob"]
  @State var minusDisabled: Bool = true
   
  var body: some View {
    Group {
      VStack(alignment: .leading) {
        Text("Test")
        TV(students: self.$students).frame(width: 400, height: 300)
        HStack {
          Button(action: {
            self.students.append("New Row")
          }) {
            Text("＋")
            }.buttonStyle(BorderedButtonStyle())
          Button(action: {
          }) {
            Text("－")
          }.buttonStyle(BorderedButtonStyle())
          .disabled(self.minusDisabled)
        }
      }.fixedSize()
      ForEach(self.students, id: \.self) { student in
        Text(student)
      }
    }
  }
}
PlaygroundPage.current.setLiveView(view().frame(width: 500, height: 800))
