[busy.org] Newly created post does not appear in the "discussion"

Repository : https://github.com/busyorg/busy
Platform : http://busy.org

Discussions should display all your posts.

After a new post is created, list of your posts (Discussion) is still old.

Once logged in, click on the right avatar image (next to notification icon). You should have at-least 1 post already.
Click on write post and create a new post.
Click Post button to publish the newly crated post. This will take you to the post page.
Now click on avatar image again to go to Discussion tab (list of your post). This will still be old list of posts and refreshing it will show newly created post.
Using My Profile link has the same effect. In fact, new post will not appear in discussion list unless site is refreshed.
