Attaching Javascript callback to ajax post editing

[Nerses_AM]

Hi,

I need to call a javascript function after the the ajax request is returned when pressing edit button. I have tried put the javascript in <script> tags in postbit_quickedit but it doesn't eval()-ed.
Also placing javascript for onFocus() event for textarea doesn't work too, as it seems that some other onfocus is attached to it.
Can you please advice how can I manage to do this. I need to call this Javascript function for enableing on-the-fly transliteration.

Thanks in advance.
