Replace <form id="typeheadForm" method="post" class="form-horizontal"> with

<?= \yii\helpers\Html::beginForm('', 'post', ['id' => 'typeheadForm', 'class' => 'form-horizontal']);?>

You are getting bad request because when you create your form manually, you did not include csrf token into it. When you create form with Html::beginForm method it takes care about it internaly.
