I want to move Add to cart button from `view.phtml` file to `2columns-right.phtml` file and I am cant make it work. What I did is that I copied `<?php echo $this->getChildHtml('addtocart') ?>` from `view.phtml` file to `2columns-right.phtml` and it does not appear at all. I did Flush Magento cache too but nothing again.

Any suggestions on how to make this work?
