use

el.onkeyup = function() { return checkNum(this); };

For the record, jQuery would have solved your whole problem like this:

$("<input/>").attr({
      type: 'text',
      name: 'cellnum_' + cnt,
      id: 'cellnum_' + cnt,
      size: 11,
      maxlength: 10,
      onkeyup: function() { return checkNum(this); }
});
