Unloading Module Closing Multiple Custom Panels

Question

I have a requirement where in  same screen can be openned N times, i have written a custom panel (module loader inside it) with a close buttonn, to load the same module multiple times. The problem is when i close one panel all the panels are closed. The reason it is closing all the panels is i have included the removeChild inside unload tag of the module loader.
I tried changing the "ml.unloadModule();" to "parent.removeChild(this);" then i acheive what is needed close only the panel that is closed, but the module it not unloaded. Is there any way i can acheive closing only a single panel (this is closed) and unload the module. 
Below is the custom panel code:
<?xml version="1.0" encoding="utf-8"?>
<s:Panel xmlns:fx="http://ns.adobe.com/mxml/2009"
                     xmlns:s="library://ns.adobe.com/flex/spark"
                     xmlns:mx="library://ns.adobe.com/flex/mx" width="436" height="340">
          <fx:Script>
                    <![CDATA[
                              [Bindable]public var url:String;
                              protected function button1_clickHandler(event:MouseEvent):void
                                        // TODO Auto-generated method stub
                                        ml.unloadModule();
                    ]]>
          </fx:Script>
          <fx:Declarations>
                    <!-- Place non-visual elements (e.g., services, value objects) here -->
          </fx:Declarations>
          <s:ModuleLoader x="10" y="9" id="ml" url="{url}" width="404" height="277">
                    <s:unload>
                              if(parent != null)
                              parent.removeChild(this);
                    </s:unload>
          </s:ModuleLoader>
          <s:Button x="411" y="-23" width="17" height="16" label="Button"
                                click="button1_clickHandler(event)" icon="assets/icon_close_down.png"/>
</s:Panel>

Instead of using an unload handler, just call both unloadModule and removeChild in the click handler.
