How to modify aler box button label for particular module ?

Here is an example

app.alert.show('message-id', {
                level: 'confirmation',
                messages: 'Is this the first call?',
                autoClose: false,
                onCancel: function () {
                    // alert("Yes!");
                    that.model.set('first_meeting_call_c', 'Yes');
                    // that._saveModel();
                    // that.cancelClicked();
                    that.handleSave();
                },
                onConfirm: function () {
                    // alert("No!");
                    that.model.set('first_meeting_call_c', 'No');
                    // that._saveModel();
                    // that.cancelClicked();
                    that.handleSave();
                }
            });
            $('.alert-btn-confirm')[0].innerHTML = "No";
            $('.alert-btn-cancel')[0].innerHTML = "Yes";
        }

Please note lines 20 & 21 where we change the labels
