[SOLVED] Uncaught ReferenceError: processString is not defined

Remember the Loading JSON from remote server example?

So I have this function


this.loadJsonFromRemote("url", this.UpdateWords);

which calls this function

Loader.prototype.UpdateWords = function(data) {
    this.processString(data);   
    this.compareArrays();
    this.generateText();
};

but when I launch the app, I get:

[Loader.js?id=7406746:88]: Uncaught ReferenceError: processString is not defined

but the function is defined in the same script!

Loader.prototype.processString = function (data) {
    //some code
};

What am I missing here, please!

EDIT:
Resolved-
this.loadJsonFromRemote("url", this.UpdateWords.bind(this));
