When you use a reload event in a field to reload another field, Chronoforms sorts out re-initialising the validation for you. But if for whatever reason you need to use AJAX to replace a field on your own, it loses its validation rules. Just put the following in your AJAX function AFTER the field is replaced.
$.G2.forms.initializeFeatures(jQuery('.ui.form'));
$.G2.forms.initializeEvents(jQuery('.ui.form'));
$.G2.forms.initializeForm(jQuery('.ui.form'));
