You can try this way with angular.copy You can write reset function. This way

  $scope.data={"a":"hello world"};
  var originalData = angular.copy($scope.data);

  $scope.data.a="changed data";

  $scope.reset = function() {
     angular.copy(originalData, $scope.data); 
  };

Instead of directly assigning it to $scope.data, do a copy of it like below :

$scope.data2= angular.copy($scope.data);

$scope.data2.a = "changed data";

angular.copy creates a deep copy of the source object which is $scope.data here.
