UPDATE Custom static block is created now, is there any way through which i can append the created block to some reference like head

In controller we can append like

    $block = $this->getLayout()->createBlock(
'Mage_Core_Block_Template',
'my_block_name_here',
array('template' => 'instagramapi/apislider.phtml')
);

$this->getLayout()->getBlock('head')->append($block);

but how to do this in my situation.
