Form validation not working after converting page to SPA

Hi all, I had a form created with validation rules that dynamically showed the validation errors etc.
However, since moving this to a SPA, the validation messages no longer appear.

My best guess is that because the page is fetched via XHR, the validation isn’t being bound to the new view. Is there any way to re-trigger this functionality on page load via XHR?

Below you can see my validation fules, but nothing appears in the browser when these rules fail.
