Make sure you are setting an error class for your elements in the data-bind attrbute of all elements being validated:

data-bind = " ...
              validationOptions: { errorElementClass: 'input-validation-error' }
              ... "

Then at the point of validation you can get all of these elements with jquery and just apply focus to the first one:

$(".input-validation-error").first().focus();
