Angularjs : Default value setting inside controller

I have a question regarding the angularjs set value and reset it to default.

Here an example

$scope.defaultValue = {
    a: 1,
    b: 2
}
var dupValue = $scope.defaultValue;

...

function changeValue() {
    dupValue.b = 3;
}

...

After I execute the function changeValue(), I wish to change my dupValue back to defaultValue which I simply just call

dupValue = $scope.defaultValue;

Some how it did't work. Because the defaultValue's element has changed due to the function i executed.

Is there any method to make this work?

You'are not copying the defaultValue, but just assigning the reference to it. Therefore when you modify dupValue you also make change to defautValue.

Assign default value using:

dupValue = angular.copy($scope.defaultValue);
