Multiple forms on one page

I have a `Settings` page with two subsections: `General Settings` and `Password Change` — two separate `<form>` tags with the `Submit` button each. When I press Submit button on any of this form I do `$scope.$broadcast('show-errors-check-validity');` to check all fields in this form... but other form is also showing errors. So, how to validate fields only for one form, not for all forms on a page?
