Add object to collection if no match

I would like to add the matched object to my collection if it is not found in the current selection, but I have found that when nothing is found the `autocompleteselect` function doesn't fire.

`"autocompleteselect input": function(event, template, doc) {
console.log(doc);
}`

I have tried using the noMatchTemplate to no success - has anyone had any luck doing this?

Start by tracing the autocompleteselect event and noMatchTemplate handling described in the issue. Determine how a selection with no current match should be represented, then verify that the object can be added to the collection and that the relevant event or template behavior works.
