I need to create an observer with creating a block on the cart table, which allow the customer to choose from radio button the options I will provide in each item separately in the product table, within the cart page and save it into the database to let the merchant see the options that his clients chose.

 <sales_quote_collect_totals_before>   <observers>   <shippingoptions>   <type>singleton</type>   <class>shippingoptions/observer</class>   <method>test</method>   </shippingoptions>   </observers>  </sales_quote_collect_totals_before> 

  public function test($observer)  {   $quote = $observer->getQuote();   $quote_items = $quote->getItemsCollection();   foreach ($quote_items as $item) { $additionalOptions = array(   array(   'title' => 'custom option title',   'type' => 'radio', // could be drop_down ,checkbox , multiple   'is_require' => 1,   'sort_order' => 0,   'values' => $this->getOptions() )   );   $item->addOption(   array(   'code' => 'additional_options',   'value' => serialize($additionalOptions), ) );   } } 

So I figure that I need to use a block to do the rendering thing, I try to do that but it didn't go well from my side. So could you help me to do that with from the observer side without overwriting the cart.phtml or any checkout file (And of course for a good reason).

Here is a screen shot just to clarify things up:
