hi,
   it seems like you will need to extend your text Component and Event class as well. Its not clear from your code that what component you are referring to . so generally you will extend your required component .
you will need to addEvent Listener
FocusEvent.FOCUS_IN
in your custom extended component and in the handler of that focusEvent you will dispatch your new custom event with the parameters from this FocusEvent you received and as well as new parameters that are also required by your new extended Event.
Method of extending events is straight forward. e.g this a sample for extending Events you will need to modify it with the paramaters you require in your event .
package
    import flash.events.Event;
    public class AccountEvent extends Event
        public var accountObj:Object
        public static var NewAccount:String='newAccount'
        public function AccountEvent(type:String,newAccount:Object)
            super(type)
            this.accountObj=newAccount
and here is the code how to use this event
package
    import flash.events.Event;
    import flash.events.FocusEvent;
    import AccountEvent
    import mx.controls.TextInput
    public class customText extends TextInput
        public function customText()
            super();
            addEventListener(FocusEvent.FOCUS_IN,onFocus)
        private function onFocus(e:FocusEvent):void{
            dispatchEvent(new AccountEvent(paramaters.....///here you will add your custom paramerters and 
           //you will catch this event in your main application rather then catching the focus in event
