W dokumentacji dla https://github.com/FezVrasta/bootstrap-material-design jest taka sekcja:

Dynamically generated elements

If you use Material Design for Bootstrap on a project handled by Angular, React or other frameworks that dynamically generate and append new elements to the document, you’ll need to manually call the Material Design for Bootstrap javascript functions to initialize new elements such as inputs.

Alternatively, you can include arrive.js before the MDB javascript to automatically initialize any dynamically generated element.

Jak to konkretnie zrobić? Piszę w Scala.js, ale przykład w zwykłym JS ES5 wystarczy.
