Pass properties from clickHandler into a TitleWindow that uses the popUpManager

Question

If there a way to pass parameters from a clickHandler that loads a titlewindow via the
popUpManager into the TitleWindow?  To begin with, I'd like to change the title based on the ow!_clickHandler.
SCRIPT
// Custom PopUp:ow1 //
private var popup:ow1PopUp = new ow1PopUp();            //ow1PopUp is a TitleWindow component//
protected function ow1_clickHandler(event:MouseEvent):void
PopUpManager.addPopUp(popup,
this, true);popup.x=110;
popup.y=110;
CLICK_HANDLER
click="ow1_clickHandler(event)"  // I'd like to be able to stuff a variable as an argument here to pass to the TitleWindow's title property.

@doug,
You can pass any number of arguments in your click handler as it is in MXML so you can do something like this...
click="ow1_clickHandler(event, 'some param')"
In order to pass this value to the PopUp create one Bindable public variable in your ow1PopUp popup component and bind it to title property of your TitleWindow component as shown below:
<mx:TitleWindow title="{titleText}">
     [Bindable]public var titleText:String="";
</mx:TitleWindow>
protected function ow1_clickHandler(event:MouseEvent, title:String):void
PopUpManager.addPopUp(popup,this, true);
popup.x=110;
popup.y=110;
popup.titleText = title;
