Custom callbacks for iziModal's close button

[Corouna]

Hi.

After using iziModal for several weeks, i just have to say i'm totally impressed with it. Smooth and easy to use modal, with almost little configurations needed to get it work to how i want it.

Just one question here. I'm currently using iziModal with header on (activated through the 'title' config), and i can see that the close button on the right side of the header, which will close the modal whenever i click on it. I'm just wondering if its possible to add custom callbacks to the close button?

I dont want to create a custom button for this, and just want to use the close button provided on the header.
