jQuery: Unbind event handler
===

I chose to go with binding element to the body to have them affecting elements even though they are not yet there. Now, I want to unbind some handlers as I go and this is where I am encountering some difficulties.  
  
Code:  

    $('body').unbind('click', deleteComment); //unbind
    $('body').on('click', '.deleteCommentButton > img', deleteComment); //binding  
  
The question is how I am supposed to unbind it specifically for `.deleteComment > img`?
