For fixing jquery popups(light box, facebox) in a page that is coming from ajax or jquery

I have a page, its contents dynamically loading using jquery/ajax. After calling the content using jquery/ajax, the popup in the page is not working. It was due to the fact that, the new elements came from ajax/jquery call not binded with the light box/ facebox. We have to reinitialize the lightbox/facebox after calling the ajax request like following:

function catdisp(val,id){
        $("#loaderimg").show();
        $.post(BASE_URL+"/catalog/categoryMultipleAjax",{filter:val,id:id},function (data){   
                document.getElementById('ajaxcat').innerHTML=data;   
                $("#loaderimg").hide();
                 $('a[rel*=modal]').facebox() ;
            });
    }
