Invalid command syntax when adding CanPlaceOn in replaceitem command

I don't know if this is a bug or I'd mistakenly type the components. I read the changelog in 1.1 and CanPlaceOn and CanBreak are available in replaceitem command. I've tried them but invalid command syntax. I've tried

{CanPlaceOn:["obsidian"]}

. If this is not a bug and I've only mistakenly type it, please comment the correct component and mark this as invalid.
