Answer
The documentation for ng-repeat says:
track by must always be the last expression
So you need to change this line:
<div ng-repeat="item in items track by $index | filter:nm" ng-hide="hide">
to this:
<div ng-repeat="item in items | filter: nm track by $index" ng-hide="hide">
I know it's obscure, and this one catches people out. Often the documentation isn't on the page you expect it to be (e.g. filter) but is still in a logical place (e.g. ng-repeat). It 'should' all be there.
