WixInstaller Custom UI template does not change installation path - wix

Question

I am having an issue in creating a custom UI template, the desired flow is:
Licence > InstallScope > install.
I have taken the WIXUI_Advanced source and changed the navigation in the below code, though when changing the selected scope, the installation path is always the default installation.
I think something is in the background happening, though I cannot find how to inject the change, all examples of this are done on the next navigation and loads a new page.
