FullCalendar - Changing hidden days with jQuery

Question

I'm filtering my calendar, I change the start and end date, status of my events, and other stuffs. I do that with:

 $("body").on("click", "#btnFiltrar", function() {
    fechaIni = $("#fechaIni").val();
    fechaFin = $("#fechaFin").val();
    cp = $("#txtCP").val();

    var events = {
        url: "./php/xxxxxxxx.php",
        type: "POST",
        data: {
            fechaIni:     fechaIni,
            fechaFin:     fechaFin,
            cp:           cp,
            provincia:    provincia,
            ...
          }
    }

    $("#calendar").fullCalendar("removeEventSource", events);
    $("#calendar").fullCalendar("addEventSource", events);
    $("#calendar").fullCalendar("refetchEvents");
});

It works fine. But when I want to change the variable hiddenDays dynamically, I can't make it work! I add to my code this: (By default this variables are global)

var dias = ["0","1","2","3","4","5","6"];
var ocultarDias = []; // is empty because it shows all days

// inside click button
diasSeleccionados = $("#selDias").val(); // returns array eg: ["1","2","3","4","5"]
ocultarDias = $(dias).not(diasSeleccionados).get(); // compare 2 arrays and get the difference

So, with that and the call fullcalendar with the attribute:

function llenarCalendario() {
     $("#calendar").fullCalendar({
        lang: 'es',
        firstDay: 1,
        hiddenDays: ocultarDias,
        ...
     });
}

I miss something? I want to do this without reload the page, just call again the function or, as the function on click button, refetchEvents or something like that. Is possible?

var newhiddendays = [0, 6];         // show Mon-Fr (hide Sat/Sun)

$('#calendar').fullCalendar('option', 'hiddenDays', newhiddendays);
