DatepickerController：

app.controller('DatePickerController',['$scope',function($scope){ 
    this.myDate = new Date(); 
    var [] newDate = ctrl.MyDate.Split(T); 
    string finalDate = newdate[0]; 
    $scope.myDate = finalDate; 
    this.isOpen = false; 
    $scope.$emit('response', $scope.myDate); 
}]); 

ReservationController：

app.controller("ReservationController",['$scope', '$http', function ($scope,$http) { 
$scope.$on('response', function (evnt, data) { 
    $scope.myDate = data; 
    }); 
$scope.insertData = function(){ 
    //window.location.href='index.html#/menu'; 
    $http.post('database/push_Reservation.php',{'username':$scope.username, 'mobile_number': $scope.mobile_number, 'mydate': $scope.myDate}) 
    .then(function(data){ 
     console.log(data); 
    }); 
    } 
}]);
