JQuery getting values ​​from sqlite database cannot update values

I made a program to insert and update records in a sqlite database and to view data in a database in Websql.

I created a text box field, and when we enter the data that it stores in the database by clicking the submit button.

I could not get the records in the database to be updated with the new values ​​entered in the text box.

However, I can insert data into the database and cannot update the values ​​in the database.

Here is my coding.

var updateStatement = "UPDATE login SET username=?,password=?,firstname = ?, lastname = ? ,hobby=?,email=? WHERE id=?";
var db=window.openDatabase('MYFORM','1.0','MYFORM',200000);

$(document).ready(function()
{
initDatabase();
$("#update").click(updateRecord);
});


function initDatabase()  // Function Call When Page is ready.

{

try {

    if (!window.openDatabase)  // Check browser is supported SQLite or not.

    {

        alert('Databases are not supported in this browser.');

    }

    else {

showRecords();

    }

}

catch (e) {

    if (e == 2) {

        // Version number mismatch. 

        console.log("Invalid database version.");

    } else {

        console.log("Unknown error " + e + ".");

    }

    return;

    }

    }
function updateRecord() // Get id of record . Function Call when Delete Button Click..

{
    var usernamenew = $('input:text[id=username]').val().toString();

    var passwordnew = $('input:password[id=pass]').val().toString();

    var firstnamenew = $('input:text[id=firstname]').val().toString();

    var lastnamenew = $('input:text[id=lastname]').val().toString();

    var hobbynew = $('input:text[id=hobby]').val().toString();

    var emailnew= $('input:text[id=email]').val().toString();

    var useridnew = $("#id").val();

    db.transaction(function (tx) { tx.executeSql(updateStatement,  [usernamenew,passwordnew,firstnamenew, lastnamenew,hobbynew,emailnew,Number(useridnew)],loadAndReset, onError) });

    }

HTML

<label for="username"> Username   :</label>

<label for="pass"> Password :</label>
<input name="password" type="password" id="pass" placeholder="your password" size="20"  maxlength="20"  width="20" />

db.transaction(function (tx) {

    tx.executeSql(selectAllStatement, [], function (tx, result) {

        dataset = result.rows;

        for (var i = 0, item = null; i < dataset.length; i++) {

            item = dataset.item(i);

              var linkeditdelete = '<ul><li>' +  item['username'] + ' , ' + item['password'] + ' ,'  +item['firstname']+' , ' + item['lastname'] +' , ' + item['hobby']+','+item['email']+ '<a href="page4.html" onclick="loadRecord(' + 'id' + ') id="edit";">edit</a>' +' '  + '<a href="#" onclick="deleteRecord(' + item['id'] + ');">delete</a></li></ul>';

            $("#results").append(linkeditdelete);
