Show alert after each function that contains tx.executeSql

Hi I have this code in javascript:

db.transaction(function (tx) {
    tx.executeSql('DELETE FROM table');
    var querys = texto.split('\n');
    $.each(querys, function(i,elem) {
        tx.executeSql(querys[i],[],null,null);
    });
    alert("DATA LOADED");
});

but my problem is that the alert is displayed before the tx.executeSql process has not finished inserting records... please help me!!!
