How to handle navigation in a MasterDetailPage using Context Actions of a ListView ?

Hello there,

I will try to give an accurate explanation for the issue I'm facing.

Context :

I'm using a MasterDetailPage for my main navigation. In a Detail page (used as a NavigationPage), I display a ListView of items. Each item can be deleted or edited through Context Actions.
The Edit Action:
I want to navigate to another page (the page which allows editing of the selected item) as a PushAsync navigation. I also tried to set a new Detail element to the RootView to navigate to my page.
Both methods are set up in the App class.

PushAsync :

public static void PushNav(Page target)
        {
            RootView.Navigation.PushAsync(new NavigationPage(target));
        }

Detail navigation :

public static void NavigateToDetail(Page target)
        {
            var rootPage = (RootView)rootView;
            rootPage.Detail = new NavigationPage(target);
        }

I tried both Command method and .Clicked event, they are both throwing errors.

var editWeezo = new MenuItem
            {
                Text = AppResources.ContextActionEdit,
                Command = new Command(() => 
                {
                    //App.NavigateToDetail(new DetailWeezoView());
                    App.PushNav(new DetailWeezoView());
                })                
            };
            editWeezo.SetBinding(MenuItem.CommandParameterProperty, new Binding("."));
            //editWeezo.Clicked += EditWeezo_Clicked;

The issue:
When I'm trying to navigate from the page after completing the context action the app crashes and it throws an unhandled exception :

Cannot undertstand the "jobject" error.

Do you have any suggestion of how to navigate in this case of use ?
