button with changing id jQuery

There is a code to add the formset for the site. You need to add a delete button for each new formset. respectively from the buttons will be the same id, and has and formseta. Please tell me how to make buttons with different id?

$('#add_issueforinvoice').on('click', function(e) {
  e.preventDefault();
  var form_count = $('#id_invoiceforproject_set-TOTAL_FORMS').val(),
      id = '#invoice_' + (parseInt(form_count)),
      prev = parseInt(form_count),
      count = parseInt(form_count) + 1,
      form_group = $('#invoice_1');

  var new_form_group = form_group.clone().prop(
    'id', 'invoice_' + count
  ).insertAfter($(id));

  $('#invoice_' + count).find('div').prop('id', function(index, id) {
    if (this.id)
      return this.id.replace('set-0-', 'set-' + (count - 1) + '-');
  });

  $('#invoice_' + count).find('select').prop('id', function(index, id) {
    if (this.id)
      return this.id.replace('set-0-', 'set-' + (count - 1) + '-');
  });

  $('#invoice_' + count).find('select').prop('name', function(index, id) {
    if (this.name)
      return this.name.replace('set-0-', 'set-' + (count - 1) + '-');
  });

  $('#invoice_' + count).find('label').attr('for', function(index, id) {
    if (this.for)
      return this.id.replace('set-0-', 'set-' + (count - 1) + '-');
  });

  $('#invoice_' + count).find('input').prop('name', function(index, id) {
    if (this.name)
      return this.name.replace('set-0-', 'set-' + (count - 1) + '-');
  });

  $('#invoice_' + count).find('input').prop('id', function(index, id) {
    if (this.id)
      return this.id.replace('set-0-', 'set-' + (count - 1) + '-');
  });
  $('#id_invoiceforproject_set-TOTAL_FORMS').val(parseInt(form_count) + 1);
