I have developed a module to overwrite a controller. I have the next route: Lecasa/Javinewlistproductcontroller/Block/Catalog/Product/List.phtml
This List.phtml file is: class Lecasa_Javinewlistproductcontroller_Block_Catalog_Product_List extends Mage_Catalog_Block_Product_List
I have been trying to use a function that I created in this List.phtml but i did not find the way to call it. Then I copied this one in Lecasa/Javinewlistproductcontroller/Helper/Data.php, I configured all files but when I used Mage::helper(...)->function(), the magento system added the Mage_ prefix to the helper class. Then, as a last alternative, I would like to know how I can call the function which is created at Lecasa/Javinewlistproductcontroller/Block/Catalog/Product/List.phtml directly from the rwd/.../List.phtml.
