I post my working solution. Thanks to @Brandon for the useful answer.

in conta.js some changes:

$(document).ready(function() {

    // avoid hard-coding urls...
    var yourApp = {
        contaUrl: "/conta/"
    };


    $('#btnGo').click(function(e) {
        e.preventDefault();  
        // set css classes and text of button
        $(this)
            .removeClass('btn-primary')
            .addClass('btn-danger disabled') // with *disabled* I'm sure that the button is not clickable
            .text('WAIT');



        $.get(yourApp.contaUrl, function(json) {     
             alert("I have finished counting");                    
             parent.window.location.reload(true);               


        });
    });
});

in views.py

def conta(request):
    c.prova(0)
    redirect = reverse('home')                  
    return JsonResponse({'redirect': redirect})
