DisclosureGroup Expandable List in SwiftUI

Question

I'm trying to close my expandable list when I click one of the item in my list. But somehow it is not triggering. I don't know where I'm making mistake. For that I'm using isExpanded Bool and when I click other items in my list im making isExpanded = false but its not working. Any idea?

struct SingleSelectionRow: View {

    @Binding var selectSingle: Int
    @Binding var selectedFilter: String?
    var title: String
    var isSelected: Bool
    var childrenList: [FilterChildren]
    @State var filterDetail: SortAndFilterData
    @State var singleSelectedFilters: [String]
    @State  var isExpanded : Bool = false
    var action: () -> Void
    @State var onClick: Bool = false

    var body: some View {

        if selectSingle == 1  {

            if childrenList.isEmpty == true {
                Button(action: {
                    self.action()
                    isExpanded = false
                    print("İS EXPANDED İS \(isExpanded)")
                }) {

                    Text(self.title.uppercased())
                        .font(.custom("DM Sans",size:15))
                        .foregroundColor(isSelected ? Color(red: 10 / 255, green: 207 / 255, blue: 131 / 255) : Color.black)
                }
            }

                        isExpanded.toggle()
                        print("İS EXPANDED İS \(isExpanded)")
                        self.action()
                    }
                }
