@Fran-Diox , thanks for your explanation.
Yes, my project is using the Onsen UI v1, but it’s possible to change the main-page content by a function on onsen ui framework?
I did it before, into a project-based in cordova 6, and worked well.
@Jonathan-Silva Hi! It’s probably a version mismatch. Make sure that the libs you are including contain the same version you were using before. If possible, update to the latest one. Monaca’s Onsen UI is not different from original Onsen UI, you can use any of them.
