Scheduling a local notification in PhoneGap/Cordova doesn't work on iOS simulator

• Installed newest Xcode (7.3.1)
• Installed newest PhoneGap (6.2.7)
• Created default PhoneGap app
• Installed local notification plugin using phonegap plugin add de.appplant.cordova.plugin.local-notification
• Added code to create notification (see below)
• Ran using phonegap run iOS
• No notification appears

Code in index.js:

document.addEventListener('deviceready', function () {
    try {
        cordova.plugins.notification.local.schedule({
            text: "This is the text.",
            at: new Date(new Date().getTime() + 10000)
        });
    } catch (e) {
        alert("Fail " + e);
    }
});

Any suggestion as to what I'm doing wrong?
