Pass button id to controller from view

Well, to complete my question.

This button open a modal i the same page.
How can i call a function in controller using a button?

It looks like you're opening a modal use javascript / jquery, so you should reference the modal docs.
If you want to pass it to a controller (on server side), make sure you put the button on a form.

P/s: Sorry for my English

Yeah, its a modal. I'm researching, but maybe only with Ajax to populate modal.

Where you from?

I'm from Vietnam.
