CKEditor edit config on the fly

Question

I have config.js file, but I also want to config some buttons dynamically. Here is my code for page:

 CKEDITOR.on('instanceReady', function (evt)
                  {

                    CKEDITOR.instances.MY_INSTANCE.destroy();
                    CKEDITOR.config.toolbar_Basic = [['Bold']];
                    CKEDITOR.config.toolbar = 'Basic';
                    CKEDITOR.config.width=400;
                    CKEDITOR.config.height=300;
                    CKEDITOR.replace('MY_INSTANCE', CKEDITOR.config);
});

when I go to the page, textarea is blinking and appears/disappears all time. What's wrong? How to change ckeditor's config dynamically ?

PS. I've seen this answer, but it didn't help me much

Use This:-

 CKEDITOR.replace( 'editor1', {
        language: 'fr',
        uiColor: '#9AB8F3'
    });
