如何从不同的控制器Yii2获取ID？

Question

In the ActiveForm I have model button with Pjax render field after form from the modal button will created. Added a picture for an example. How can I get newly created id (not select added to the database, need to get the id that comes from this form).

I think I need to set get to button, than with ajax catch this and transfer to my Pjax rendered cell

I tried variations, but unsuccessfully, I cann't fully understand how to implement it. Can anyone help with the solution ?

//TwoController
public function actionCreate()
{
    $model = new Formtwo();

    if ($model->load(Yii::$app->request->post())) {
        if ($model->save()) {
            echo 1;
        //maybe here I must to do query ?
        } else {
            echo 0;
        }
    } else {
        return $this->renderAjax('create', [
            'model' => $model,
        ]);
    }
}

    //TwoController
public function actionCreate()
{
    $model = new Formtwo();

    if ($model->load(Yii::$app->request->post())) {
        if ($model->save()) {
            echo $model->id;
        //maybe here I must to do query ?
        } else {
            echo 0;
        }
    } else {
        return $this->renderAjax('create', [
            'model' => $model,
        ]);
    }
}

You don't need query. Just use $model->id. It has value after save().

Update

It doesn't matter in which controller you are. You get the id of the model saved after save(). Then you can use id attribute. So, you can open modal form with ajax load. On form2 you register script to ajax post form. Something like this:

$("#form :submit").click(function (e) {
            e.preventDefault();
            $.ajax({
                method: "POST",
                url: $("#form").attr("action"),
                data: $("#form").serialize(), 
                success: function (response) {
                    $("#modalid").modal("hide")
                    $.pjax.reload({
                        container: "#grid"
                    });
                   $('#Form2_id').val(response); //here you get the id
                },
            })
            return false;
      });
