MapAnnotation button action not working (SwiftUI 2.0 Map)

I'm just trying to touch on the map annotations, but the button's action is not working. I've tried to figure how to solve it but nothing so far. I'm wanting to use the Map without make de UIKit bridge.

Here is my map:

Map(coordinateRegion: $locationManager.currentLocation,
    interactionModes: .all,
    showsUserLocation: true,
    userTrackingMode: $trackingMode,
    annotationItems: $locationManager.annotations.wrappedValue) { location in
        MapAnnotation(coordinate: location.coordinate, anchorPoint: CGPoint(x: 0.5, y: 0.5)) {
            MapAnnotationView(name: location.title, image: Image("dog"))
        }
    }

And here is my MapAnnotationView:

import SwiftUI

struct MapAnnotationView: View {
    var name: String
    var image: Image
    @State var size: CGFloat = 20

    var body: some View {
        VStack {
            Button(action: {
                size = $size.wrappedValue == 20 ? 60 : 20
                print("TAPPED =====>")
            }, label: {
                image
                    .resizable(capInsets: EdgeInsets(), resizingMode: .stretch)
                    .frame(width: $size.wrappedValue, height: $size.wrappedValue, alignment: .center)
                    .clipShape(Circle())
                    .overlay(Circle().stroke(Color.white, lineWidth: 2))
                Text(name)
                    .font(.caption)
                    .fontWeight(.semibold)
                    .foregroundColor(.primary)
            })

        }
        .shadow(radius: 5)
    }
}
