Sheet not updating Parent View - mvvm

Question

When I modify the score using the stepper on View1 it successfully updates the score on View1.ViewModel. However when I dismiss the sheet it does not update the score on the players section.
I know that you can set #Binding var on Player1 but how do I pass this down to the View1.ViewModel so that when it makes changes it updates the parent view?
ContentView
import SwiftUI
struct ContentView: View {
#State var game: Game = Game(name: "Game #1")
#State var isPresented: Bool = true
var body: some View {
NavigationView {
List {
Section(header: Text("PLAYERS"), content: {
ForEach(game.players) { player in
HStack {
Text(player.name)
Spacer()
Text("\(player.score)")
}
}
})
}
.navigationTitle(game.name)
}
.sheet(isPresented: $isPresented, onDismiss: {}, content: {
TabView {
ForEach(game.players) { player in
View1(player: player)
}
}
.tabViewStyle(PageTabViewStyle())
})
.onAppear(perform: {
for p in 1...3 {
let player = Player(name: "Player #\(p)")
self.game.players.append(player)
}
})
}
}
struct View1: View {
#ObservedObject var vm: View1.ViewModel
init(player: Player) {
vm = ViewModel(player: player)
}
var body: some View {
VStack {
Spacer()
Text(vm.name)
Divider()
Group {
Stepper("Earned Points: \(vm.earnedPoints)", value: $vm.earnedPoints, in: 0...50)
}
.padding(.horizontal)
Spacer()
}
}
}

get {return self.round.earnedPoints}
set {self.round.earnedPoints = newValue}
}
}
}
