Collect value of a Bean in an HTML

Good Morning,

I am doing my first tests with Polymer and the Bean of CUBA and I have a question that I can not solve. I have made a Bean, which simply returns the String called “name” “Hello World” and then in my HTML I am doing the following ->

EY! -> [[BeanName.name]]

But when I launch the app, do not pick up the “Hello World” I want, just the “EY! ->” appears, any suggestions?

Thank you very much,
Greetings.

Hello,

What do you mean by Bean? Is it middleware service?
