Confused with reply_markup

[iMasoud]

Hi. I'm trying to change Keyboard after sending a photo, this is my code:

...
api.sendPhoto(
{
chat_id: message.chat.id,
caption: '',
photo: 'img/help.png',
reply_markup: {"keyboard" : [['help more!'],['cancel']]}
}, function(err, data)
{
...

and this is the console output:
{}

can you give me an example about syntax of "reply_markup", please?

thank you and excuse me for my bad English
