Your code has no form tag and your commandButton has no process attribute.

One way to achieve this is, you will need to capture the keycode and check if it is enter event (keycode = 13 ) and trigger click event on the button you desire which will submit the form and invoke the associated backing bean action method. Please see Default action to execute when pressing enter in a form
