This function handles events for any UI that looks like
this:
[pill-enabled input box for subscribers] [Add button]
In an ideal world the above two widgets would be enclosed in
a <form>...</form> section and we would have a single submit
handler, but our current implementation of input pills has
some magic that prevents the pills from playing nice with
the vanilla HTML form/submit mechanism.
So, instead, we provide this helper function to manage
the two events needed to make it look like the widgets
are inside an actual HTML <form> tag.
This abstraction also automatically retrieves the user_ids
from the input pill and sends them back to the `action`
function passed in.
The subscriber input-pill widgets lets you provide
user_ids by creating pills for either:
* single user
* user group
* stream (i.e. subscribed users for the stream)
