title: Cannot trigger alt store with alt action (Flux)
body: <p>I'm developing a flux frontend program with <a href="https://github.com/goatslacker/alt" rel="nofollow">goatslacker/alt</a>. And I have problem triggering store to update with action. The listener is not functioning as I expected it to be.</p>
  
  <p>The code I'm working on is quite complicated now. I'll try to simplify my problem into the following code. I expect it to log "Hello World! msg: Some message" in the end. Apparently, the listener <code>hello()</code> doesn't even run.</p>
  
  <p>This is the main javascript (ES6) file to be run:</p>
  
  <pre class="lang-js prettyprint-override"><code>import alt from './alt';
  
  class DummyActionsProto {
  
    sayHello(msg) {
      console.log("sayHello", msg);
      return {msg}
    }
  
  }
  var DummyActions = alt.createActions(DummyActionsProto);
  
  class DummyStoreProto {
  
    constructor() {
      this.bindListeners({
        hello: DummyActions.sayHello,
      });
  
      this.state = {
        items: [],
      };
    }
  
    hello(msg) {
      console.log("Hello World! msg: "+msg);
    }
  
  }
  var DummyStore = alt.createStore(DummyStoreProto, 'DummyStore');
  
  // trigger the action
  DummyActions.sayHello("Some message");
  </code></pre>
  
  <p>The ordinary <code>alt.js</code> code it includes:</p>
  
  <pre class="lang-js prettyprint-override"><code>import Alt from 'alt';
  module.exports = new Alt();
  </code></pre>
  
  <p>What is my problem?</p>
