ActionScript 3.0 :: Jobs Listing - How To Remove / Delete Task

I am basically creating an application that prioritizes jobs listing, so far I can assign a task priority, description. So basically once the task description and task priority is chosen, the user will click the add button, and this will be stored in the database and on the screen another mc will appear where the created priority and description assigned will be display. In the mc there will also be a delete button to remove/delete the task. What code could I use to remove the task...

So far I have typed the following
mc.task_mc.delete_btn.addEventListener(MouseEvent.CLICK, onDeleteClick);
private function onDeleteClick(e:MouseEvent):void {
}
