Uncaught TypeError: this.dispatch is not a function

Is the TypeScript tutorial over at https://github.com/goatslacker/alt-tutorial/tree/master/src up to date? Getting some errors following that tutorial and wondering what I'm doing wrong. Trying to use to dispatcher but it apparently doesn't exist.

Typescript: 1.8.2

```
"use strict";
import alt = require("./alt");

/**
* AltJS Flux Actions implementation
{@link http://alt.js.org/guide/actions/} AltJS Actions
*/
class myActions implements AltJS.ActionsClass{
constructor(alt: AltJS.Alt) {

}

dispatch: (...payload: Array) => void;

myAction(payload : any): void {
this.dispatch(payload);
}

}

export = alt.createActions(myActions);
```

Start with the TypeScript tutorial under https://github.com/goatslacker/alt-tutorial/tree/master/src and compare its ActionsClass and createActions usage with the AltJS API. Reproduce the reported this.dispatch error using TypeScript 1.8.2, then determine whether the tutorial needs correction or an explanation of the supported usage.
