add a callback function in loadmodal

[JeffreyChan]

I think your load-modal is really pretty.

But I need some custom function in this.

Put it in simple way, if I load a page for add a entity, I want to after create entity done, close modal, and notify the main page , then do something else.

If doesn't have a callback function, how do I know the modal is closed by cancel button or confirm button?

The other question is how do I close modal inside, not in main page.

Any Idea on this ?
