EFL UI bascially works on main loop with only one thread. So EFL system can't draw UI until you finish your some job in your event function. You can make another thread for your job and start thread in the event function. But use ecore idle functions for using eext_circle_object_value_set. Most EFL and tizen function must be used in main thread. So run your job in another thread and request progress value setter to main thread with ecore main loop functions.

EFL Ecore supply sync and async function for request job to main loop. ecore_main_loop_thread_safe_call_async and ecore_main_loop_thread_safe_call_sync can be used instead of ecore_idle functions.

So here is simple example with Elementary progresses. I don't use eext functions in this source but you can refer elm_progressbar_value_set instead of eext.
