Dave - I’m not sure this is correct to replace the $scope.field_or_function with an unscoped version.  All of the angular sample code I’ve seen has used the $scope prefix and it seems to save me from the mysterious ‘this variable or function is not in scope here’ type issues.  Are you sure all this code is functional when event handler start calling it such that the scope is ambiguous?
