Binding a module's width to the caller

Question

I've been trying to bind a module's size to the caller's
container's size. How do I do this correctly? Should I create an
event listener in the module?
I have the following fragment in the app.
<mx:ModuleLoader id="myTrendChartModule"
url="modules/MyChart.swf"
width="{MyVBox.width}" height="350"
verticalScrollPolicy="off"/>
It does bind the width initially. But, it doesn't bind when I
resize the app. I have to add " resize="OnResize()" " in the
<mx:Application>. And, I have to call a chart function to
resize it there.

Plus, it wouldn't call my redraw chart functuion if I max or
resize the browser by using the browser button. I am kinda lost.
Can anyone give me some details behind?
I should treat the moduler as common componments on the
application. And, I should specify the following in the module:
<mx:Module .....
height="100%" width="100%"/>
And, it will automatically adjust itself, rite?
If I want to redraw my chart, the function should be called
during resize in the main app?
