Recover info from logged in user

Hi,
I need to recover from a DB more information from users using DB Read:

In the OnLoad Event
I've created a Custom Code (that give me the id of online user)

<?php
$user = \JFactory::getUser();
$form->data['online_id'] = $user->id;
?>

and the DBRead configured as below
Table name: y90ms_users
Multi read:Yes
Enable Model ID:Yes
Model ID: *empty*
Fields: id, username, email
Conditions:<?php return array('id' => data['online_email']; ?>

When I test the form I receive the Array below:

Array
(
    [option] => com_chronoforms5
    [chronoform] => TEST_ReadDB
    [online_user] => test_user@gmail.com
    [Data] => Array
        (
            [0] => Array
                (
                    [id] => 12
                    [username] => test_user
                    [email] => test_user@gmail.com
                )
        )

)

and this one the Debug Info

Array
(
    [24] => Array
        (
            [DB Read] => Array
                (
                    [Queries] => Array
                        (
                            [0] => SELECT `Data`.`id` AS `Data.id`, `Data`.`username` AS `Data.username`, `Data`.`email` AS `Data.email` FROM `xbduhikb_Jumpers` AS `Data` WHERE `Data`.`email` = 'test_user@gmail.com'
                        )

                )

        )

)

Seems that DB Read found my online user email on DB.

Now, if I want write some fields(id, username, email) of user in a text Box, witch sintax I need to use?
I've tried [email] or {email} or [data.email]....but doesn't work.

Thanks
