Buttons will not show up for tasks_group_object_tasks in a cycle where i...

...s_current is false.
Will the same pattern work if `using` isn't used, or will `inserted` already be triggered by the time the scriptlet runs?

Can we add a `jQuery.fn` `$(el).when_inserted(function(){...})` or something to make it uniform?

(Not in this PR, just an August wishlist, maybe?)
