Custom fields wont show on quick edit

Hi,

i downloaded this plugin because i need to be able to edit one of my custom fields in the quick edit mode. With this plugin, i can see the custom field appears on one of the columns, but its uneditable which is useless. What can i do so i get to edit the field?

Thank you.
