How can I count checkbox check from many forms

I want to count how many boxes checked. I am having trouble because it counts all the checkbox checks, but I want to count checkboxes from each arcticle and show it on there seprate boxesChecked div. article01 checks = boxesChecked-01,article02 checks = boxesChecked-02. I tried diffrent id's method to know where to innerhtml() count, but as you can see that dosent work

var form = $(".checkform");
var checkBoxes = $(form).children('.checkbox');
var count = 0;


$(checkBoxes).on('click', function() {
  var id = $(form).attr("id").split("-")[1]

  $.each(checkBoxes, function(i) {
    if (checkBoxes[i].checked) {
      count++;
    }
  });

  var divBoxesChecked = document.getElementById('boxesChecked-' + id);
  divBoxesChecked.innerHTML = 0;
  divBoxesChecked.innerHTML = count;
  count = 0;
});
