javascript - Multiple variables using $watchGroup -

-

my watchgroup isnt working, gives me undefined, doing wrong in code?

 $scope.$watchgroup([vm.footer.nrrows, vm.issaved], function(current, original) {              console.log("nr rows "+current[0]);             console.log("is saved? "+current[1]);         });

change code this: 

$scope.$watchgroup(["vm.footer.nrrows", "vm.issaved"], function() {    ... }, true);

if variable $scope.something should put in $watch "something"
