You didn't include how you define handle_edit_action, but I assume you
use @formlib.form.action here as well:

    @formlib.form.action(u'Edit')
    def handle_edit_action(self, action, data):
        ...

What this code does is to create a new Action object, having the
handle_edit_action method as its success method. This action will be
added to self.actions, but more importantly, this action will also be
assigned to self.handle_edit_action. So in your handle_applyAndClose
method above, self.handle_edit_action isn't a method, it's an Action
object. (c.f the way @property works). So in order to call your edit
action you need to do:

    self.handle_edit_action.sucess(data)
