ajax submit problem with IE7 / IE6

hello!

i develop my own CMS with a textmodul based in the "mooEditabel" and the subitted data is send via ajax. in firefox 3 everthing runs smooth just the IE7 and IE6 makes trouble with the ajax request.

what exactly happens: 1. i type in the textfield of "mooEditable" the word "hello" the i click submit. 2. the return of the alert command is empty! 3. then i type instead of "hello" the word "hello2" and click submit again. 4. the return of the alert command is "hello"

Important: if i remove the $('text').mooEditable(); the hole thing runs perfekt in all browsers. the text will be send by an ajax request smoothly but without the "mooEditable" fuctionality.

i hope you can understand what the problem is. i have atached the complete source files with the test-setup of the textmodule.
