Why FB.login doesn't ask me for permissions

Why FB.login doesn't ask me for permissions

When I try to publish something with the following code:
FB.login(function(response) {
if (response.authResponse) {
FB.api('/me/feed','post',{
name: "Nombre",
link: "http://radio/player/bbc_world_service",
description: "This is test",
message : "xxxxxxxx"
},function(response) {
//
});
}else {
//
}
},{scope: 'publish_actions','user_likes'});
It doesn't ask me for any permissions, just publishes in my timelime
directly. As far as i know theoretically it must ask me for permissions.
But i try to do the same thing through facebook explorer, it does ask for.
