Is it correct to use ajax request in the model?

Question

JavaScript

Hello! I would like to get a code review of this model!
The project uses mvc and in the model there is an increase / decrease in the value in the methods and sending an ajax request with this value, and then writing the received response from the server back to the model constructor, and then manipulate them in the future!

class TestModel {
    constructor() {
        super();
        this._result = {
            count: 1,
            product: 0,
            allPrice: 0
        };
    }

    getItems() {
        return this._result;
    }

    addItem(result) {
        const params = {
            evt: 'countAdd',
            result: result
        }
        // увеличиваем count на 1
        this._result.count = result.count + 1;
        // и передаём его в ajax запрос
        this.getAjax(this._result.count, params);
    }

    remItem(result) {
        const params = {
            evt: 'countRemove',
            result: result
        }
        this._result.count = result.count - 1;
        this.getAjax(this._result.count, params);
    }

    getAjax(count, params) {
        const _this = this;
        $.ajax({
            url: 'send-test.php',
            type: "POST",
            dataType: "html",
            data: {'count': count},
            success: function (response) {
                // получаем ответ и результат записываем в конструктор модели
                // от куда потом через метод getItems получаем данные для вывода во View
                var result = $.parseJSON(response);
                _this._result.all = result.allPrice;
                setTimeout(() => {
                    _this.emit(params.evt, params.result);
                }, 100);
            },
            error: function (response) {
               console.log('fail!');
            }
        });
    }
}
export default TestModel;

Logically, it looks correct. The model is responsible for working with data
Since you have mvc in js, I can suggest using axios instead of jquery
