Spotify Connect Binding

Today i’ve changed from the older 2.3.0 binding to the new 2.5.0. binding. Everything was quick and easy after setting up the player bridge and change the Thing ID in my items.
But one thing doesn’t work, that was working on 2.3.0. I have a button on my habpanel sending INCREASE or DECREASE to spotify_player_deviceVolume. I see the command is received:

14:05:45.679 [INFO ] [smarthome.event.ItemCommandEvent ] - Item ‘spotify_player_deviceVolume’ received command INCREASE

But the volume isn’t changing. Is this available in the new binding? I’ve red that every binding need the manually add this option:
