<method>

Attaches a function or event handler to an object or class. Attaches a method to the object that contains this element. The method must have a name.

The name attribute allows the method to be invoked from JavaScript with this name. For example, if a method is defined via: 

<view id="obj">
 <method name="f" args="a, b">
   return a+b;
 </method>
</view>

then script code can invoke obj.f(1, 2) to add two numbers.
