Map does not have parseModel (ajax convert)

I'm having a bug pop up. this.parseModel is undefined. This happens when an ajax request completes in jQuery, and CanJS has a proxy to convert the response to a model. In this case, "this" represents the CanJS "Map"

jquery.js - Callback for a completed ajax request...

complete( // complete === jquery.js done
  xhrSuccessStatus[ xhr.status ] || xhr.status, // 200
  xhr.statusText, // "OK"
  ( xhr.responseType || "text" ) !== "text"  ||
  typeof xhr.responseText !== "string" ?
    { binary: xhr.response } :
    { text: xhr.responseText }, // {text: '{"name": "value"}'}
  xhr.getAllResponseHeaders() // Pragma: no-cache, etc.
);                          

jquery.js - done

response = ajaxConvert( s, response, jqXHR, isSuccess );
// ajaxConvert === jquery.js ajaxConvert
// s === (ajax options)
// response === {error: "SyntaxError: Unexpected token o in JSON", state: "parsererror"}
// jqXHR === jqXHR...
// isSuccess === true

jquery.js - ajaxConvert:

response = conv( response ); 
// response ==={error: "..."}
// conv === can/proxy.js class_cb

can/construct/proxy/proxy.js - class_cb

cur = (isString ? self[func] : func).apply(self, cur || []);
// self = Map
// func = "model"
// cur = [{error: "..."}]

Which essentially translates to:

Map.model.call(Map, {error: "..."})

can/model/model.js - model

attributes = this.parseModel(attributes, xhr);
// this === Map
// attributes === {error: "..."}
// xhr === undefined
// this.parseModel === undefined

How can I get "Map" to have "parseModel"?

It appears that this may be a work-around...

attributes = function(attributes){
    return function (attributes) {
        return prop ? can.getObject(prop, attributes) : attributes;
    };
};
//attributes = this.parseModel(attributes, xhr);

@lewismoten Anyway you can create an example? Moving to can-model.
