How to hang Yandex. Goals on Formit Ajax?

Question

JavaScript

Good afternoon.
Tell me who faced such a problem. How to hang the Yandex. Goals on the form. The form itself is implemented in Formit Ajax. (MODX REVO).
If you hang the target code on the onclick event, then with any click on the input, the target is fulfilled, but it is only necessary when the form is successfully submitted.
Thanks in advance.
