Adding block to a single page on dashboard

Developing with Concrete
1

Hello

I am trying to add an accordion block to a single page which is on dashboard. I am using Concrete CMS v9.0.

So I have added this to my controller:

    $page = Page::getCurrentPage();
    $block = BlockType::getByHandle('accordion');
    //set block data (differs for each block type... following is an example for the 'content' type)
    $data = array(
        'title' => '<h3>title here</h3>',
        'description' => '<p>description here</p>',
    );
    $page->addBlock($block, 'Main', $data);

And this to my view:

 <?php
     $a = new Area('Main');
     $a->enableGridContainer();
     $a->display($c);
 ?>

But it does not create the block as I wanted. It has just a empty div. What do I miss here? Any help is appreciated. Thanks.

Maybe I should rephrase my question. Is it somehow possible to use blocks in single pages for dashboard?
