Yes @Ankur Bawiskar  its not working.

From below code we are not getting response value .

function handleCompletedAsmt(g_form) {

    g_modal.showFrame({

        url: "change_risk_completed_asmt_dialog.do",

        title: "Risk Assessment Complete",

        size: "md",

        preferences: {

            displayValue: g_form.getDisplayValue(),

            focusTrap: true

        },

        onClose: function(response) {

            if (response === "yes") {

                // Allow user to resubmit the form

                g_form.setValue('state', 'new'); // or appropriate state

                g_form.save(); // or g_form.submit()

            } else {

                g_form.addInfoMessage("Risk assessment remains unchanged.");

            }

        }

Kindly suggest. we are getting UI page on form when we click on Risk Assessment but Yes or No input is not coming up,
