How to add an confirmation window on ng-click Angular

I have a link with ng-click. I need a confirmation window on that click.

<h4><a href="" ng-click="makeUnfavourite(favourite.userId,$index);remove(favouriteData.data.result,$index)">Un-Favourite</a></h4>

currently it includes 2 functions. I have to execute this two functions only after confirmation. my two functions are defined in usercontroller.js.plz see code below

var userControllers = angular.module('userControllers', ['ui.bootstrap','gm']);
userControllers.controller('myProfileCtrl', function ($scope, $routeParams, $rootScope, $http, $location, $window, $timeout) {`  
$scope.makeUnfavourite=function(id,index){
    var indextoremove=index;
    var currentuserid=2;
    var favUserId=id;
    console.log(favUserId);
    var params = {
        currentuserid:2,
        favUserId:id
        };
       if(favUserId){
        $http.post($rootScope.STATIC_URL + 'users/makeUnFavourite', params).success(function(response){
            $scope.favHide=response;
            }).error(function(err){
            console.log("Error"+err);
        });
    }

};
$scope.remove = function(favourite,index){
    favourite.splice(index,1);
};
});

I have to execute makeUnfavourite() & remove() function on confirmation.I am fresher in angular. Now I am working in a partially finished project

It is easy, you have 2 functions

<a confirmed-click="makeUnfavourite(favourite.userId,$index)" ng-confirm-click="Confirm unfavorite?">Un-Favourite</a>

Now you could call $scope.removefunction inside makeUnFavorite, or, inside confirmed-click, like this:

<a confirmed-click="makeUnfavourite(favourite.userId,$index);remove(favouriteData.data.result,$index);" ng-confirm-click="Confirm unfavorite?">Un-Favourite</a>

I prefer first solution. Complete code:

Controller

var userControllers = angular.module('userControllers', ['ui.bootstrap','gm']);
userControllers.controller('myProfileCtrl', function ($scope, $routeParams, $rootScope, $http, $location, $window, $timeout) {`  
$scope.makeUnfavourite=function(id,index,favourite){
    var indextoremove=index;
    var currentuserid=2;
    var favUserId=id;
    console.log(favUserId);
    var params = {
        currentuserid:2,
        favUserId:id
        };
       if(favUserId){
        $http.post($rootScope.STATIC_URL + 'users/makeUnFavourite', params).success(function(response){
            $scope.favHide=response;
            //here we call the remove function, always inside the $http response for not having async issues
            $scope.remove(favourite,index);
            }).error(function(err){
            console.log("Error"+err);
        });
    }


};
$scope.remove = function(favourite,index){
    favourite.splice(index,1);
};
});

HTML

<a confirmed-click="makeUnfavourite(favourite.userId,$index,favouriteData.data.result)" ng-confirm-click="Confirm unfavorite?">Un-Favourite</a>

EDIT

One more thing, it would be better if you use on $http.post this structure:

$http.post($rootScope.STATIC_URL + 'users/makeUnFavourite').then(function(response){
     //Ok response stuff
}, function(error){
     //Error response stuff
});
