Enable quickedit action for “post_content” on both Question & Answer admin pages

Hi,
We have been using DWQA pro for a couple of years, and now we need our editors/admins to be able to directly edit the post_content from the quickmenu action on Questions admin page as well as Answers admin page. 
I have created a custom column to display the content, but my efforts to make it quick-editable has been unsuccessful.
I would really appreciate it if you could guide me on how to do this.
Thanks in advance.
Ebrahim
