Will help you a callback
The function that should be invoked to implement the primary function.

Problem solved
$(".doska").bind( 'DOMSubtreeModified',function(){ // track the content change unit 2
 var summ = 0;
 $(".tovar #doscen").each(function(){

 summ += parseInt($(this).html(), 10) ;
 $('#skolko').html(summ +'Tg');
 $("#cenazakaza").html(summ +'Tg');
