Angular filter in controller

Well I know this question has been asked before and already had an answer. Here it is: TheQuestion

Actually it can't work for me and I tried a lot but failed. This works fine:

<ng-repeat="item in myList | filter:item.visible=true ">

And I tried this as TheQuestion said:

$scope.myList = $filter('filter')($scope.myList, { item.visible: true});

I also tried this one:

var isOpen = function(item) {
  return item.visible == isOpen;
}
$scope.myList = $scope.myList.filter(isOpen);

Both of them cannot work for me. Did I miss something?

Here is a plunker may help. Please don't undevote it. Thanks.
