Add attribute to list/grid category page in magento 1.9

Question

I want to add a selector for attribute in magento 1.9, in the list/grid page. I tried some online guide, but don't work with new magento 1.9, can anyone help me ? thanks

After any changes with products and attributes you first need do reindex. And then check the same code as 1.8. New 1.9 Magento has a problem with reindex after any changes.
