HTML events in calendar (FW7 V7)

Hello! I’m migrating my apps from V5 to V7 and now I’m struggling with calendar events. On V5 I could load from a remote JSON and render the events using HTML and it parses ok.

Now on V7 it does not render as HTML and as a plain text. Check the picture:

There’s something I need to do to parse them as HTML?
