Status updates from JomSocial do not currently get pushed back to Facebook. This is something on our radar, but it is not a current feature of JFBConnect. Currently, FB status updates only on registration or login based on what you set in the admin area. With 3.0, we've made the ability to publish status updates much simpler and we're working with some 3rd party devs to implement status updates on certain events in their components. We'll also be adding easy ways for an admin to hook into certain things to post to a user's wall as well.
