Why SwiftUI `confirmationDialog` delete the wrong item?

I am trying to use confirmationDialog to delete an item in a List. But what happens is that the wrong item gets deleted. Why?

Here is my code:

struct MyView: View {

   @State private var selectedUsers: MyModel?
   @State var datas: [MyModel]
   @State private var confirmDelete = false

    var body: some View {
        
            ScrollView(.vertical, showsIndicators: false, content: 
   { 
                
                VStack(content: {
                    
                    ForEach(datas){ data in
  
                        MyRowView(data: data)
                         
                            .contextMenu {

                                Button(action: {
                                    self.delete(item: data)
                                }) {
                                    Text("delete") 
                                }
                               
                            }
                            .onTapGesture {
                                selectedUsers = data
                            
                            }
                   .alert(isPresented: $confirmDelete) {
              Alert(title: Text("title"),
                message: Text("message"),
                primaryButton: .destructive(Text("Delete")) {
               
                self.delete(item: data)
                 
                },
                secondaryButton: .cancel())
            }
                 
           
                    } .onDelete { (indexSet) in
                       self.datas.remove(atOffsets: indexSet)
                    }})
           })}

    private func delete(item data: MyModel) {
               if let index = datas.firstIndex(where: { $0.id == data.id }) {
                   datas.remove(at: index)
               }
           }}
