Writing an angularJS directive to modify a dynamically created element behaviour and including it in the referencing template

It might be a very basic question, but I'm not getting how to work around the following.

I've a template which uses angular JS with jQuery to dynamically create an element. Among those elements for certain elements I need to control the tabindex(navigation using TAB key) behavior. For this I prefer to write a directive and include its invoke in the template. How can we do that?
