New additions stories are not added to the modal view

[cawa-93]

In my script, story should load later, after the user opens the modal preview window.

What I expected:
After adding a new story, it will be available in modal view. And the user will get to it when viewing the latest of the pre-loaded history.

What's really going on:
To view newly loaded stories, user must close the modal viewer window and reopen it.
