Cordova script is not executed

I got some script that seem to not be executed but I don't know why, I'm trying to debug this with the IOS simulator and safari to see the log.

Here is the content of the index.html

<html>
<head>
    <meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *">
    <meta name="format-detection" content="telephone=no">
    <meta name="msapplication-tap-highlight" content="no">
    <meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width">
    <link rel="stylesheet" type="text/css" href="css/index.css">
    <title>Test</title>
</head>
<body>

    <div id="appContainer" class="app">
        <h1>Apache Cordova</h1>
        <div id="deviceready" class="blink">
            <p class="event listening">Connecting to Device</p>
            <p class="event received">Device is Ready</p>
        </div>
    </div>
    <script>
      alert('Wait!'); // is not working
    </script>
    <script type="text/javascript" src="cordova.js"></script>
    <script type="text/javascript" src="js/index.js"></script>
</body>

and here is the content of the index.js

alert("wait"); // That one is working, why ?

var app = {
// Application Constructor
initialize: function() {
    console.log("app init");  // not working
    this.bindEvents();
    console.log("app init end");  // not working
},
// Bind Event Listeners
//
// Bind any events that are required on startup. Common events are:
// "load", "deviceready", "offline", and "online".
bindEvents: function() {
    console.log("bind start");  // not working
    document.addEventListener("deviceready", this.onDeviceReady, false);
    document.addEventListener("click", this.onClick, false);
    console.log("bind end");  // not working
},
// deviceready Event Handler
//
// The scope of "this" is the event. In order to call the "receivedEvent"
// function, we must explicitly call "app.receivedEvent(...);"
onDeviceReady: function() {
    console.log("device start");
    app.receivedEvent("deviceready");
    document.getElementById("appContainer").addEventListener("click", this.onClick, false);
    document.getElementById("appContainer").addEventListener("touchstart", this.onClick, false);
    document.getElementById("appContainer").addEventListener("touchend", this.onClick, false);
    console.log("device end");
},
// Update DOM on a Received Event
receivedEvent: function(id) {
    var parentElement = document.getElementById(id);
    var listeningElement = parentElement.querySelector(".listening");
    var receivedElement = parentElement.querySelector(".received");

    listeningElement.setAttribute("style", "display:none;");
    receivedElement.setAttribute("style", "display:block;");

    console.log("Received Event: " + id);
},
onClick: function(e) {
    console.log("click"); // not working or it may be the eventlistener
},

};

console.log("init s"); // not working
app.initialize();
console.log("init e"); // not working

What I dont understand is 1 - Why the alert("Wait") in index.html is not working. 2 - Why the console.log doesn't work execpt the device start, device end and Received Event: deviceready 3 - Why the app.initialize don't seem to be executed (because there are no log) but is actually executed because the device ready event is fired 4 - Why can't I see the log in the onClick function when I trigger a click in the simulator (if the device ready event work, click, touchstart and touchend should work no ?)

Can somebody explain to me why nothing seems to work properly ?

I'm using cordova 5.3.1 with almost no modification from the init package. I tried to remove ios and add it again but it doesn't change anything.

Thank for the help

The "console" global is an Apache Cordova plugin. It will only be available ondeviceready. Have a look here http://plugins.cordova.io/#/package/org.apache.cordova.console

Try this

var app = {
    initialize: function() {
        console.log("app init");
        this.bindEvents();
        console.log("app init end");
    },
    // Bind Event Listeners
    bindEvents: function() {
        console.log("bind start");
        document.addEventListener("click", this.onClick, false);
        console.log("bind end"); 
    },
    onDeviceReady: function() {
        console.log("device start");
        app.initialize();
        app.receivedEvent("deviceready");
        document.getElementById("appContainer").addEventListener("click", this.onClick, false);
        document.getElementById("appContainer").addEventListener("touchstart", this.onClick, false);
        document.getElementById("appContainer").addEventListener("touchend", this.onClick, false);
        console.log("device end");
    },
    receivedEvent: function(id) {
        var parentElement = document.getElementById(id);
        var listeningElement = parentElement.querySelector(".listening");
        var receivedElement = parentElement.querySelector(".received");

        listeningElement.setAttribute("style", "display:none;");
        receivedElement.setAttribute("style", "display:block;");

        console.log("Received Event: " + id);
    },
    onClick: function(e) {
        console.log("click"); // not working or it may be the eventlistener
    },

};

//initialize app on device ready
document.addEventListener("deviceready", app.onDeviceReady, false);

As for your "alert" mystery, window.alert compatibility has been proven unreliable in the context of Cordova. I advise you to use

navigator.notification.alert

Which is part of plugin-dialogs https://www.npmjs.com/package/cordova-plugin-dialogs

On a side note, there are better ways to manipulate DOM and CSS if that's your goal.
