Styles, Format, Fonts and Size lists are all going to disappear when I reload page with AJAX

I load my forms with AJAX calls and CKEditor is implemented via PHP code in them. After submitting my form with jQuery form plugin, I go for another area of administration e. g. "Pages". This way the old form which consisted the CKEditor will be replaced by new set of contents which it is "Pages" right now. When I try to load another form which includes CKEditor in it, the four lists in toolbar would appear blank when I click on each of them. I don't use destroy() or remove() to delete previous instances because I didn't see any difference and would someone tell me how to implement CKEditor in AJAX based applications properly? I'm not sure that I'm doing this right.
