Context issue in userProfile(token, done)()

[bgbahoue]

I created a class that inherits from one of the predefined Passport strategy (OAuth2 from passport-oauth) to be able to add some specific code. I ran into an issue with the context (this) that is set in the userProfile() method (call by the internal passport logic to create the user's profile)

Is there a workaround to be able to get / pass-on a reference of my GenericOAuth2Strategy ?

Thanks in advance

--- My code (simplified) ---

function GenericOAuth2Strategy(name, options, verify) {
    // do something
    this._name = "my name";
    OAuth2Strategy.call(this, options, verify);
}

require('util').inherits(GenericOAuth2Strategy, OAuth2Strategy);

GenericOAuth2Strategy.prototype.myFunction() {
    // In here this is not equal to my current GenericOAuth2Strategy
    console.log(this);
    console.log(this._name); // => this throw an error see below
    console.log(this.getName()); // => this throw an error see below
}

GenericOAuth2Strategy.prototype.userProfile = function(accessToken, done) {
    this.myVar = 'toto';
    this.myFunction(); // this is called
}

--- Console output ---

This = { success: [Function],
  fail: [Function],
  redirect: [Function],
  pass: [Function],
  error: [Function],
  myVar: 'toto' }

When I try to access 'this._name' I get this error

This._name = undefined

When I try to access 'this.getName()' I get this error

GenericOAuth2Strategy.js:xx
console.log("This._name = %s", this.getName());

TypeError: undefined is not a function
