How to call method when new revision of Item is created

Thank you so much for you reply. I add my logic of start workflow in that if condition it works fine, but the life cycle state of the item will not promoted when I complete my task. It should get change from In work to review, so for that we have to promote life cycle through coding? and  one more question after workflow gets start from coding, when task is created in My Inbasket, the Worked Item is showing Restricted.
