Selectable doesn't work on newly added rows.

[pod2metra]

I'm using grappelli and nested inlines, newly added inline row don't do anything while typing, but if this inline has already been saved, then on reload this page all completions will work correctly.

    $(document).on('formset:added', function(event, $row, formsetName){
      window.bindSelectables($row);
    });

I try to handle add new line via this snippet, but window.bindSelectables does nothing.
