This is waving a massive red flag for me. The template loop is
evaluated when it is output, so if you really want to call the
javascript function on each iteration of the loop, what you're
effectively doing would be calling it immediately the page reaches the
browser. Why would you want to do that? It sounds like you're putting
some of the responsibility for building some of the page into
Javascript, which is a very bad idea (what about those people with JS
turned off, or on mobile phones without JS support, or using
screenreaders?)
Much better would be to do whatever logic is required within the view
or the template itself, and leave Javascript for adding extra
functionality.
