angular .$save is not a function

My project is base on ionic framework, and I am using ngResource in project. Now my requirement is that I want to pass the url dynamically to that ngResource function. For this I create one wrapper for this. And its working properly with get, put, getone method but I have an issue while submitting data to the server and I got this error .$save is not a function. Check this code for more detail.

Wrapper

angular.module('ClientAPI.services', [])
.factory('ClientAPI', function ($resource) {
    var _passUrl;
    var _passParameters;

    return{
        passUrl:_passUrl,
        passParameters: _passParameters,
        callAPIClient : function(){
            return  $resource( this.passUrl, this.passParameters, {
                'update': {
                    method: 'PUT'
                }
            })
        },
        setURL: function(url){
            this.passUrl = url
        },
        setParameters: function(params){
            this.passParameters = params;
        }
    }

})

Use in Code :

$scope.movie = new ClientAPI.callAPIClient();
    $scope.addMovie = function () {
        $scope.movie.$save(function () {
            $state.go('app.movies');
        });
    }
