app.js

 var validationApp = angular.module('validationApp', []).config(function ($interpolateProvider) {
    $interpolateProvider.startSymbol('<%').endSymbol('%>');
});

validationApp.controller('mainController', function ($scope, $compile) {
    $scope.log = function () {
        console.log($scope.userForm);
    };
    /*
     * If is selected partnership will show button for adding partners.
     */
    $(".category").click(function () {
        var value = $(".category option:selected").val();
        var token = $('.csrf').val();
        var solo = 1;
        var partnership = 2;

        if (value == solo || value == '') {
            $('.partner-button').hide();
            $('.inputs').remove();
        } else if (value == partnership) {
            $('.partner-button').show();
            //$(".input_fields_wrap").append(fields);
            //$compile(fields)($scope);
        }
    });

    /*
     * Adding fields for partner.
     */

    var count = 0;
    $('.add_field_button').click(function (e) {

        e.preventDefault();
        var input = $("<div class=\"inputs\">" +
            "<input type=\"text\" ng-model=\"partnerName" + count + "\" name=\"partners[" + count + "][name]\" placeholder=\"Наименование на партньор\" required/>" +
            "<p ng-show=\"userForm['partners[" + count + "][name]'].$error.required\" class=\"errors\">Наименованието на партньора е задалжително</p>" +

Answer 1

You could use ngForm which is "an alias" (if you don't take into consideration that ng-submit doesn't work with ng-form ) of form in order to group the steps together.

This way each ngForm with a defined name, much like form , will get its own form controller thus allowing you to use ng-disabled="firstStep.$invalid" , ng-disabled="secondStep.$invalid" etc.
