Update parent scope variable in AngularJS

Question

I have two controllers, one wrapped within another. Now I know the child scope inherits properties from the parent scope but is there a way to update the parent scope variab

Answer 1

For accessing variables declared in the parent, we should use $parent in child controller or template file

In controller

$scope.$parent.varaiable_name

In html template

ng-model="$parent.varaiable_name"
