I have a Modal Popup on my Page. Usually, when a Modal pops up the entire background is blurred but I have a scroll button that shows up on the Modal Popup. I used fadeOut() on it when the action completes so it doesn't appear on the Dialog box. Now what I want to do is, to find out if this popup was closed so I can show that button again using fadeIn(). Is there a way I can know when My Modal Dialog closes so I can show the scroll button again?

Here is how I faded it out:

function CallOfferRenderAction(productCode, providerCode) {
    $("#loading").show();

    // TO OPEN OFFER DETAILS
    var urlOfferDetails = $('#OfferDetails').val();
    $.ajax({
        url: urlOfferDetails,
        type: 'POST',
        data: { 'offerID': productCode, 'providerId': providerCode },
        closeBtn: 'true',
        success: function (data) {
            $("#loading").hide();
            $.fancybox(
            {
                'href': '#offerPopup',
                'content': data,
                'hideOnOverlayClick': false,
                'hideOnContentClick': false,
                'autoScale': false,
                'overlayShow': true,
                'type': 'iframe'
            });
        },
        error: function (req, status, error) {
        },
        complete: function () {
            $("#loading").hide();
            $('.scrollup').fadeOut();
        }
    });
}
