I am using bootstrap-ui more specifically modal windows. And I have a form in a modal, what I want is to instantiate form validation object. So basically I am doing this:
I use the documented approach.
https://docs.angularjs.org/guide/forms
so, user the form name, on "save" click for example just pass the formName as a parameter and hey presto form available in save method (where formScopeObject is greated based upon the ng-models specifications you set in your form OR if you are editing this would be the object storing the item being edited i.e. a user account)
