An example would be good here. An example of how to make something bindable, and bind to it, entirely in actionscript, not mxml.

There are examples in the doc here:

Can I have a working example on defining a binding to a setter function in actionscript? Let's say I want to implement this in actionscript:

<mx:Binding source="myTextInput.text" destination="handleChangeText" />

private function set handleChangeText( newText: String ): void {...}

Thanks

Here's an example using bindSetter():

<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">

<mx:Script>
<![CDATA[

import mx.binding.utils.*;
import mx.events.FlexEvent;

<!-- Event listener to configure binding with a setter. -->
public function mySetterBindingInline(event:FlexEvent):void {
var watcherSetter:ChangeWatcher = BindingUtils.bindSetter(function(v:String):void { taSetter1.text = v}, tiSetter1, "text");
}

// Set method.
public function setMyString(val:String):void {
taSetter2.text = val;
}

<!-- Event listener to configure binding with a setter. -->
public function mySetterBinding(event:FlexEvent):void {
var watcherSetter:ChangeWatcher = BindingUtils.bindSetter(setMyString, tiSetter2, "text");
}
]]>
</mx:Script>

<mx:Panel title="My Application" paddingTop="10" paddingBottom="10"
paddingLeft="10" paddingRight="10" >

<mx:Label text="Bind Setter using inline setter"/>
<mx:TextInput id="tiSetter1" text="Hello Setter" />
<mx:TextArea id="taSetter1" initialize="mySetterBindingInline(event);"/>


<mx:Label text="Bind Setter using setter method"/>
<mx:TextInput id="tiSetter2" text="Hello Setter" />
<mx:TextArea id="taSetter2" initialize="mySetterBinding(event);"/>

</mx:Panel>
</mx:Application>

The documentation for bindProperty() is incorrect. If an Object is specified for the chain object, the name of the property containing the accessor function should be "getter" not "access".

You are correct: the property name is 'getter'. This is also true for the ChangeWatcher.watch() method.
