How to collect all fields in angular.js?

Question

Angular

Let me know who is facing it.
I understand angular.js, before that I only worked with jquery.
The essence is this: there is a block in which there are 2 selects and 3 checkboxes. When changing any input (be it a select, or a checker), an Ajax request with these parameters should leave.
I rendered the elements like this:

<select name="inspection" ng-change="change()" ng-model="formData.inspection">

And checkboxes

<input type="checkbox" 
      ng-model="formData.power1" 
      ng-change="change()"  
      ng-true-value={{ p.pk }}
      ng-checked="true"

So, the checkers are all marked, but they are not included in the object. After changing the checker or select, the object is filled with the required fields.
jquery has a serialize() method that iterates over the entire form and generates the selected options.
Is there a similar equivalent in angular.js?
It is clear that you can manually select each value in the controller and assign it to the request object. But this is a jquery-way, but I want to somehow optimize everything. To click on the select, and all fields are automatically assigned to the object.
Thank you

Answer 1

Try ng-change="change(formData)" like this.

Hang $watch on formData:

$scope.$watch('formData', function () {
            // submit $scope.formData;
        }, true);
