Check and Uncheck Checkbox Dynamically with jQuery : bug?

Question

I made a script in order to control master & slave checkboxes (automatic checking and unchecking).

Here is my JS :

$(document).ready(function() {

I wrote you a plugin for this:

$.fn.dependantCheckbox = function() {
  var $targ = $(this);
  function syncSelection(group, action) {
    $targ.each(function() {
      if ($(this).data('checkbox-group') === group) {
        $(this).prop('checked', action);
      }
    });
  };
  $('input[type="checkbox"][data-checkbox-group]').on('change', function() {
    var groupSelection = $(this).data('checkbox-group');
    var isChecked = $(this).prop('checked');
    syncSelection(groupSelection, isChecked);
  });
}
$('input[type="checkbox"][data-checkbox-group]').dependantCheckbox();
