Solve the following python programming problem given the following code:
@ staticmethod 
def boolean(is_report = False, **kwargs) : 
    '
        Shortcut to render booleans as a check mark if true or blank if false.
        ' 
    def render_icon(value) : 
        if callable (value) : 
            value = value () 
return (mark_safe ('<i class="fa fa-check" title="Yes"></i>') if value else '') 
setdefaults (kwargs, dict (cell__format = (lambda table, column, row, value : (yes_no_formatter (table = table, column = column, row = row, value = value) if is_report else render_icon (value))), cell__attrs__class__cj = True, query__class = Variable.boolean, bulk__class = Field.boolean)) 
    return Column (** render_icon) 

    
    

    Fix the buggy line: return Column (** render_icon)
