remove databind

 mylistbox.databind(); 

you don't need since adding item list collection. if setting datasource property, have use it. depending on in life-cycle update firing well. update being replaced code somewhere else in process well.

in truth, take out of being separate thread. since need updated before page submits information browser, either need keep in same thread make sure completes, or you're going need have sort of check @ end of page executing process make sure has finished. possible thread completing after page has finished processing.
