I copied and pasted your code in one of my views. I just changed your model so I am using one of my models (tables). Your code works perfectly in my view. So I think you should check if the problem is one of these:

1. You are not correctly importing one of these:

   use backend\models\Developers;

   use yii\jui\AutoComplete;

   use yii\web\JsExpression;

2. Your table Developers is empty

3. In the part of your code that says:

   ->select(['name as value', 'name as label','developer_id as id'])

   Are you sure your table developer has the columns name and developer_id?
