YII2 Collect data from different checkbox to one field

I have very weird behaviour of the checkbox. I am doing a page in YII2 where I have some checkbox with different options, I need to collect all of them and add to Data Base. My problem is that I can't collect any data. the view have this form.

  <?php $form1 = ActiveForm::begin(); ?>
    <?= 
         DetailView::widget([
        'model' => $model,
        'condensed' => false,
        'enableEditMode' => false,
        'hover' => true,
        'labelColOptions' => ['style' => 'width:20%; text-align:left !important; '],
        'mode' => DetailView::MODE_VIEW,
        'vAlign' => DetailView::ALIGN_MIDDLE,
        'valueColOptions' => ['style' => 'vertical-align: middle; '],
        'panel' => [
            'heading' => Yii::t('api', 'Description_a'),
            'type' => 'company',
        ],

        'attributes' => [
            [
                'group' => true,
                'label' => Yii::t('api', 'actions_grup1'),
                'rowOptions' => ['class' => 'info']
            ],
     ['label' => Html::checkbox('101', false, ['label' => Yii::t('api', 'Action1')]),
                'value' =>Yii::t('api', 'Description_1'),
            ],
     ['label' => Html::checkbox('102', false, ['label' => Yii::t('api', 'Action2')]),
                'value' =>Yii::t('api', 'Description_2'),
            ],
          ],
        ],
    ]);
           <?= Html::a(Yii::t('api','create_new'), ['controller/create'], ['class' => 'btn btn-success' ]) ?>       
      <?php ActiveForm::end(); ?>

even that all check box on definition have false on inspect I can see the * value="1"* and also in the function create in controller I have just one this now

 $post=Yii::$app->request->post();
var_dump($post);
exit;

the $post is array(0) { } no meter if I click or not to some checkbox to be checked Can someone tell me what I am doing wrong? Or what I am missing?
