Cordova / SQLITE

I am trying to implement a simple example using Cordova and sqlite Database

here is my js code:

 var dbName = "PresentationDB";
 var dbVersion = "1.0";
 var bdSize = 100000;
 var displayName = "TTPresentationDB";
 var db = null;

 var app = {

// Application Constructor
initialize: function() {
    this.bindEvents();
},
// Bind Event Listeners
//
// Bind any events that are required on startup. Common events are:
// 'load', 'deviceready', 'offline', and 'online'.
bindEvents: function() {
    document.addEventListener('deviceready', this.onDeviceReady, false);
},
// deviceready Event Handler
//
// The scope of 'this' is the event. In order to call the 'receivedEvent'
// function, we must explicitly call 'app.receivedEvent(...);'
onDeviceReady: function() {
    app.receivedEvent('deviceready');
    db = createdb();
    alert("DB Created");
    db.transaction(populatedb,errorCallBack,successCallBack);

   },
// Update DOM on a Received Event
receivedEvent: function(id) {
    //var parentElement = document.getElementById(id);
    //var listeningElement = parentElement.querySelector('.listening');
    //var receivedElement = parentElement.querySelector('.received');

    //listeningElement.setAttribute('style', 'display:none;');
    //receivedElement.setAttribute('style', 'display:block;');

    console.log('Received Event: ' + id);
}



};

app.initialize();


function createdb(){

if (!window.openDatabase)
{
  alert("Your browser does not support openDatabase");
}
 alert("creating db..");
 return openDatabase(dbName, dbVersion, displayName, bdSize);

}


function populatedb(tx){

tx.executeSql('CREATE TABLE IF NOT EXISTS PAGE (id_page INT AUTO_INCREMENT                  

PRIMARY KEY,title VARCHAR(255), description TEXT, num_visits DATE,   
last_visited DATE)');
tx.executeSql('CREATE TABLE IF NOT EXISTS CONTENT (id_content INT       

AUTO_INCREMENT PRIMARY KEY, FOREIGN KEY(id_page) REFERENCES PAGE(id_page))');
tx.executeSql('CREATE TABLE IF NOT EXISTS ARTICLE (id_article INT  

AUTO_INCREMENT PRIMARY KEY, title VARCHAR(255), text TEXT, description TEXT,  
FOREIGN KEY(id_page) REFERENCES PAGE(id_page))');

tx.executeSql('INSERT INTO PAGE (title, description, num_visits, last_visited)          
VALUES ("First Page", "Test Page", CURRENT_TIME, CURRENT_TIME)');
tx.executeSql('INSERT INTO CONTENT (id_page) VALUES (1)');
tx.executeSql('INSERT INTO ARTICLE (title, text, description, id_page) VALUES   
("Article 1 Page 1", "Test Article", 1)');
tx.executeSql('INSERT INTO ARTICLE (title, text, description, id_page) VALUES 
("Article 2 Page 1", "Test Article", 1)');

}

function successCallBack()
{
  alert("Sucess");
  //alert("Returned rows = " + results.rows.length); 
}


function errorCallBack(tx, err)
{
    alert("Error : " + err );
}

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

}

The lines when there is AUTO_INCREMENT and THOSE where i try to insert Data into the Data Tables are causing this undefined error

Any Help ?
