AngularJS directive $scope.$watch for two way binding doesn't working

I am trying to detect changes on two way binding scope in AngularJS (1.7.2) directive.
// pagination.js (directive)
app.directive("pagination", ($rootScope) => {
return {
templateUrl: "/shared/filters/pagination/pagination.html",
scope: {
filter: "="
},
link: function($scope, element, attrs) {
$scope.$watch("filter", value => {
console.log(value); // first time works, later it's undefined
});
}
}
});
// parent.html
<pagination filter="filter"></pagination>
// parent.js
$scope.filter = {
status: "All"
};
The $scope.filter is getting changed via function, which also locate in the parent.js file:
$scope.someFunction = () => {
$scope.filter.status = "Pending";
// this should fire the $scope.$watch event in the pagination.js (directive)
// however this doesn't get applied
};
How to make the scope to be listened to changes that are coming from other directives?

Use a deeper watch depth:
$scope.$watch("filter", value => {
console.log(value); // first time works, later it's undefined
̶}̶)̶;̶̶
}, true);
For information, see AngularJS Developer Guide - $scope
