How to use debounce function with CanJS DefineMap view-model method?

I'm trying to use lodash _.debounce function for canjs DefineMap view-model method but it seems that this is tricky even I tried to do it in the init method but without success:

export const ViewModel = DefineMap.extend({
 init() {
  this.myMethod = _.debounce(this.myMethod, 200)
 },
 myMethod() {
  // cool stuff here
 }
})

Any help is appreciated!

Because DefineMap's are sealed by default, and you likely want independent throttling with respect to individual instances of ViewModel, you want to do it like this:

var time = new Date();

var ViewModel = can.DefineMap.extend({
 id: "number",
 myMethod: {
   type: "any",
   default(){

     var fn = _.debounce(function(){
       console.log(this.id+" says Hi at "+(new Date() - time))
     },100);
     return fn;
   }
 }
});

This basically sets the myMethod property to a debounced function. You can see it in action here: http://jsbin.com/nekelak/edit?html,js,console
