OROCRM Datagrid cell template ignored in DatagridListener using datagridConfig addColumn() method - datagrid

Question

I have an OROCRM application and there is a datagrid, needs to be extended with a column named by userNames, and intented to display data in a custom twig cell.
To maintain this i made a DataGridListener class and in it a method to extend columns:
/**
* Creates specific column names for selected persons
*
* #param Datagrid $datagrid
* #param array $persons
*
* #return array
*/
protected function addColumnsForPersons(Datagrid $datagrid, array $persons): array
{
$config = $datagrid->getConfig();
$additionalColumns = [];
foreach ($persons as $person) {
$column = [
'label' => $person->getName(),
'template' => 'MyBundle:Partials/Datagrid/Attendance:person_attendance.html.twig',
'type' => 'twig',
'frontend_type' => 'html',
'data_name' => 'person_' . $person->getId(),
'data' => 'person_' . $person->getId(),
'translatable' => false,
'editable' => false,
'align' => 'middle'
];
$config->addColumn('person_' . $person->getId(), $column);
$additionalColumns[] = 'person_' . $person->getId();
}
return $additionalColumns;
}
I add also data for person by the following:
$wrapperData = $datagrid->getData();
foreach($attendancesAtDay as $attendance) {
// This block can be changed to a workaround
$dayData['person_' . $attendance['personid']] = (object)([
'arrival' => Carbon::createFromFormat('Y-m-d G:i:s', $attendance['arrival'])->format('H:i'),
'leave' => Carbon::createFromFormat('Y-m-d G:i:s', $attendance['leave'])->format('H:i'),
'logins' => $attendance['logins'],
'worktime' => gmdate('H:i', $attendance['worktime'] * 60)
]);
}
$gridData[] = $dayData;
$wrapperData->setData($gridData);
The template is reachable and PHPStorm can follow its link from reference, and is the following:
<div>
<div style="width:40px">
{{ value.worktime }}
</div>
<div style="width:40px">
{{ value.arrival }}
</div>
<div style="width:40px">
{{ value.leave }}
</div>
<div style="width:40px">
{{ value.logins }}
</div>
</div>
With this method i got the columns named by person, but with empty data. With xdebug the code never goes into the template.
With some workaround if i change the block in the foreach it renders needed data.
The workaround is the following:
$dayData['person_' . $attendance['personid']] = sprintf(
'<table>
<tr>
<td>
Worktime
</td>
<td>
Arrival
</td>
<td>
Leave
</td>
<td>
Logins
</td>
</tr>
<tr>
<td>
%s
</td>
<td>
%s
</td>
<td>
%s
</td>
<td>
%s
</td>
</tr>
</table>',
gmdate('H:i', $attendance['worktime'] * 60),
Carbon::createFromFormat('Y-m-d G:i:s', $attendance['arrival'])->format('H:i'),
Carbon::createFromFormat('Y-m-d G:i:s', $attendance['leave'])->format('H:i'),
$attendance['logins']);
I tried to use array instead of object without success, or any error message in var/logs/dev.log .
I wanted to avoid this workaround, and wondering why don't throws error in case i added booth twig template to column and html code as data, and why doesn't runs into the cell template?
So what do i wrong?
Thanks for any help!
