Put ActiveForm in Gridview Column Yii2 - yii2

Question

How can put an ActiveForm in a gridview column? The following is the code I made: I tried to render the page such that it includes the active form which I need.
'columns' => [
[ 'format' => 'html',
'value'=> function($data) { return Html::img($data->imageurl) . " <p class='feedback-username'>" . $data->username . "</p>"; },
'contentOptions'=>['style'=>'width: 30px; height: 30px'],
],
[ 'format' => 'raw',
'value' => function($model) { return "<p class='feedback'>". $model->KOMENTAR ."</p><br><p class='feedback-date'>". $model->TANGGAL ."</p><hr><div id='replay-". $model->ID_KOMENTAR."'><ul></ul></div>";},
],
[ 'format' => 'raw',
'contentOptions'=>['style'=>'width: 5px;'],
'value' => function($model) {
if($model->id == Yii::$app->user->identity->id) {
return Html::a('<i class="glyphicon glyphicon-share-alt"></i>',null,['id'=> 'replay-to-'. $model->ID_KOMENTAR ]).' '.
Html::a('<i class="glyphicon glyphicon-pencil"></i>', ['update', 'id' => $model->id]).' '.
Html::a('<i class="glyphicon glyphicon-trash"></i>', ['delete', 'id' => $model->id], ['data' => ['confirm' => 'Do you really want to delete this element?','method' => 'post']]);
}
return Html::a('<i class="glyphicon glyphicon-share-alt"></i>',['feedback', 'id' => $model->id],['id'=> 'replay-to-'. $model->ID_KOMENTAR ]);
},
],
[
'content' => $this->render('feedback_test'),
],
But I got this error:
PHP Warning – yii\base\ErrorException
call_user_func() expects parameter 1 to be a valid callback, function '
<div class="feedback-form">
<p>test</p>
</div>' not found or invalid function name
How do I include the active form in the grid view's column?

Answer 1

Try this.
[
'content' => function($model, $key, $index, $column) {
echo $this->render('feedback_test');
OR
echo $this->render('feedback_test', ['model' => $model]);
},
],

Answer 2

The above answer outputted the form above my grid. I wanted the form in one of my columns for every row of data. I ended up customizing an ActionColumn like this:
[
'class' => 'yii\grid\ActionColumn',
'template' => '{map}',
'contentOptions' => ['class' => 'text-center'],
'buttons' => [
'map' => function ($model) use ($m, $r) {
return $this->render('_form', ['model' => $m, 'req' => $model, 'ref' => $r]);
},
],
'urlCreator' => function ($action, $model) {
if ($action === 'map') {
return $model;
}
},
]
