Solve the following python programming problem given the following code:
def render_tag(self, tag_func) : 
    '
        Creates a tag using the decorated func as the render function
        for the template tag node. The render function takes two
        arguments - the template context and the tag token.
        ' 
    @ wraps (tag_func) 
    def tag_wrapper(parser, token) : 
        class RenderTagNode (template.Node) : 
            def render(self, context) : 
                return tag_func (context, token) 
return RenderTagNode () 
return self.tag (tag_func) 

    
    

    Fix the buggy line: return self.tag (tag_func)
