InsertHtml problem with appending code

Hi there,

I try to append simple block of code into editor, but when I try to do that like this : 

CKEDITOR.instances.description.insertHtml('<div class=\'club\'><div class=\'foto\'><img src=\'/public/images/default/tempImg.png\' /></div><div class=\'desc\'><h2>Name</h2><p>Description</p></div></div>')

And I make changes like name, description, and call that again, the code is inserted inside the div I already insterted. 

Is there a way to append html at the end of editor every time?
