Ajax error when using sqlite plugin in phonegap

I'm making a phonegap app which reads json data from external server via ajax. I need to load and save data in a sqlite database. Native sqlite generates an callback function error about which I asked on stackoverflow but didn't get any answer. I decided then to use a sqlite plugin but when I use it in my app, error function defined in ajax executes. Without plugin, it works well. Please tell me how I can use sqlite with or without plugin without any error. Here's the code I'm using:

              var DB = window.sqlitePlugin.openDatabase({name: "Posts_DB.db"});
              var BASE_URI = "http://ift.tt/1PZwZie";
         var POST_OFFSET = 0;


             function getPosts() {
          $.mobile.loading('show');

            $.ajax({
                    url: BASE_URI + "posts",
                     type: "GET",
                       dataType: "json",
                    data: {
                     "number": 10,
                      "offset": POST_OFFSET,
                       "order": "DESC"
                      },
                  error: function() {
                   alert("An error occured.");
                    },
                   success: function(response) {
                   $.each(response.posts, function(index, data) {
                   $('<li><a href="#single" data-transition="slide" id="'+data.ID+'"><h1>'+data.title+'</h1><p>'+getDays(data.date)+'</p></a></li>').appendTo('#latest-list');
                   $(document).on("click", "#"+data.ID, function() {
                showPost(data.title, data.date, data.content, data.URL);
                   });
              });
                $('#latest-list').listview('refresh');
             $.mobile.loading("hide");
                }
              });
         POST_OFFSET+=10;
        }
          document.addEventListener("deviceready", onDeviceReady, false);
        function onDeviceReady() {
        $(document).ready( function() {
        DB.transaction(createTableDB, errorCB, successCB);
         getPosts();
        });
        }

           function createTableDB(tx) {
             tx.executeSql('CREATE TABLE IF NOT EXISTS Posts(id INTEGER PRIMARY KEY AUTOINCREMENT, Title TEXT NOT NULL, Date TEXT NOT NULL, Content TEXT NOT NULL, Link TEXT NOT NULL)');
              }

           function populateDB(tx) {
               var title = document.getElementById('entry-title').innerHTML;
              var date = document.getElementById('entry-date').innerHTML;
              var content = document.getElementById('entry').innerHTML;
               var url = document.getElementById('browser').getAttribute('href');
               tx.executeSql('INSERT INTO Posts(Title,Date,Content,Link) VALUES(?,?,?,?)', [title, date, content, url] );
               }


              function errorCB(err) {
                alert("Error processing SQL: "+err.message);
               }


                function successCB() {
                   DB.transaction(queryDB, errorCB);
                }


                 function queryDB(tx){
                   tx.executeSql('SELECT * FROM Posts', [], querySuccess, errorCB);
                  }

             function querySuccess(tx,result){
               $('#saved-articles-list').empty();
              for( var index = 0; index < result.rows.length; index++) {
                     var row = result.rows.item(index);
                    $('#saved-articles-list').append('<li><a id="'+row['id']+'" data-transition="slide" href="#single"><h1 class="ui-li-heading">'+row['Title']+'</h1><p class="ui-li-desc">'+getDays(row['Date'])+'</p></a></li>');
                   $(document).on("click", row['id'], function() {
                    showPost(row['Title'], row['Date'], row['Content'], row['Link']);
             });
           }

           $('#saved-articles-list').listview("refresh");
       }
