Solve the following python programming problem given the following code:
def AddPlugin(self, plugin) : 
    composerCommand = (composer + ' global require ') 
    command = '{0} {2} && {1} plugin add {2}'.format (composerCommand, cli, plugin) 
    stream = subprocess.Popen (command, shell = True, stdout = subprocess.PIPE, stderr = subprocess.STDOUT) 
    def OnAdd(retcode) : 
        if (not retcode) : 
            server.restart () 
            editor.notify ('Plugin installed') 
else : 
            if (retcode == 127) : 
                editor.error (pathError) 
editor.error ('Plugin installation failed') 
def LogAdding() : 
        retcode = stream.poll () 
        if (retcode is not None) : 
            return OnAdd (retcode) 
line = stream.stdout.readline () 
        editor.log (line) 
        return True 
editor.callAfter (0.0001, OnAdd) 

    
    

    Fix the buggy line: editor.callAfter (0.0001, OnAdd)
