$scope.Contacts = $meteor.collection().subscribe does not refresh the scope

Hi there all angular-meteor/meteor & angular gurus.

I am really new to angular-meteor and facing the following problem. I perform a search using

$scope.Contacts = $meteor.collection(Contacts,false).subscribe(‘searchString’, $scope.searchString);
$scope.Contacts = $scope.$meteorCollection(Contacts,false).subscribe(‘searchString’, $scope.searchString);

and the $scope.Contacts does not refresh. It seems like its holds the old collection. I can see the data being returned by the mongo server and they look fine.If I iterate through the collection using $meteor.foreach you can see that the data are there.

But once the first search result is assigned to $scope.Contacts it wont refresh any more. I am having the feeling that $scope.Contacts keeps its own “collection” and only append new rows/docs comming from $meteor.collection.

Any help would be greatly appreciated.

Thanks All,
