Clear item not working when using custom template and typeahead

[andreasfranz]

Expected behaviour

When using the option [multiple]="true" in combination with a custom template it should be possible to remove single selected items after filtering with typeahead.

Actual behaviour

It does not work and throws an error on the console. Without a custom template it works fine. Looks like an issue with the clearItem function.

I created a Plunker that shows the issue.

1. click into the select box and search for a term that is not in the list.
2. try to remove a single item by clicking on the "x" next to the item

More Info

ng-select version: 0.20.1

browser: Google Chrome 64.0.3282.140

reproducible in provided Plunker
