        $li = $chk.closest('li'),
        $ul, $parent;
    if ($li.has('ul')) {
        $li.find(':checkbox').not(this).prop('checked', this.checked)
    }
    do {
        $ul = $li.parent();
        $parent = $ul.siblings(':checkbox');
        if ($chk.is(':checked')) {
            $parent.prop('checked', $ul.has(':checkbox:not(:checked)').length == 0)
        } else {
            $parent.prop('checked', false)
        }
        $chk = $parent;
        $li = $chk.closest('li');
    } while ($ul.is(':not(.someclass)'));

Answer 1

your Bootstrap version wasn't working, because the checkbox items are located in different place relative to the ul element ($ul = $li.parent();) that is used for searching the item. Your Bootstrap version:

  <div class="checker"> 
      <span class="checked">
          <input type="checkbox">
       </span>
  </div>President
  <ul>...

The original Fiddle version:

   <input type="checkbox" />President
   <ul>

I changed your Fiddled code slightly to take into consideration your changed element location in your Bootstrap version:

 do {
    $ul = $li.parent();
    //$parent = $ul.siblings(':checkbox'); old code
    $parent = $ul.siblings('.checker');
    if ($chk.is(':checked')) {
        $parent.find(':checkbox').prop('checked', $ul.has(':checkbox:not(:checked)').length == 0)
    } else {
        $parent.find(':checkbox').prop('checked', false)
    }
    $chk = $parent;
    $li = $chk.closest('li');
} while ($ul.is(':not(.someclass)')); 

The working sample can be found at Bootply Fiddle.

Btw, your original Fiddle sample code was cool, it used a recursive loop in cool way to obtain parent elements :-)
