How does Wax call lua functions such as function tableView_numberOfRowsInSection?

[Chuanli Gan]

function tableView_numberOfRowsInSection(self, tableView, section)

  return #table.keys(self.state)

end

How does Wax call this function by the name "tableView_numberOfRowsInSection"?Is it called by "tableView.numberOfRowsInSection"?But I can't find the calling code.

Thanks!
