                $.scrollableView.add(pagingmain);
 
 
            page[$.scrollableView.getCurrentPage()].setBackgroundColor("#ddd"); //set the initial colour
 
            // I Attach the scroll event to scrollableView, so we know when to update things

                if (e.currentPage || e.currentPage == 0) {

                    for (var c = 0; c < pageLength; c++) {
                        page[c].setBackgroundColor("#000");
                    }
                    // Bump the Color of the new current page
                    page[e.currentPage].setBackgroundColor("#ddd");
 
                }
                });
