Cordova android:在onsenui中无限滚动从数据库加载数据

我正在开发一个与Onsenui和Cordova在android的混合移动应用程序，我想在主页上显示一些数据，并加载更多的项目时向下滚动。我知道这是用ons-infinite-scroll完成的这是我所尝试的

<ons-scroller
       infinit-scroll-enable="true"  can-load="true" on-scrolled="populateList()" threshold="2" style="height:100%">
<div ng-repeat="item in items">
 //display the data
</div>
</ons-scroller>

Js

module.controller('AppController', function($scope,$http) {
   //for initial loading
   $scope.items=new Array();
   $scope.page=1;
    $http.get(url+"getlotterylist").then(function(msg){
        $scope.loading=false;
        $scope.items=msg.data;
    });
 //load more when scrolls down
     $scope.populateList=function(){

        $http.get(url+"getlotterylist&&page="+$scope.page).then(function(msg){
            $scope.items=msg.data;
             $scope.page +=1;
    });
    }
}

实际的问题是，当向下滚动它取代旧的数据与新的 .我怎么能解决它?另外，我想在获取所有数据后停止滚动

function get_lottery_list(){
    $limit=7;
    $page=(isset($_GET['page']))?$_GET['page']:1;
    $start=($page-1)*$limit;
    $connect=db_connect();
    $result=$connect->prepare("SELECT * FROM `daily_draw_details` ORDER BY `id` DESC LIMIT $start,$limit");
    $result->execute();
    echo json_encode($result->fetchAll(PDO::FETCH_ASSOC));
  }
