<form class="form-horizontal" role="form" name="form-name" id="form-name" >

    <textarea class="ckeditor" name="cktext" id="cktext"></textarea>

 <button type="submit" class="btn btn-default btn-success">Submit</button>

  $(document).ready(function(){

        $("#form-id").validate(
        {
            ignore: [],
          debug: false,
            rules: { 

                cktext:{
                     required: function() 
                    {
                     CKEDITOR.instances.cktext.updateElement();
                    },


                }
            },
            messages:
                {

                cktext:{
                    required:"Please enter Text",
                                       }
            }
        });
    });

You can use like below

 CKEDITOR.instances['id'].on('focus', function () {
   //Do something here.
 });

you can pass any valid event here.
