PhoneGap/Cordova v5 addEventListener click event not waiting for click

Question

Hello Fellow Developers, I am new to PhoneGap, have not coded in a number of years, and have an issue with the addEventListener below.

The alert which i am sampling in the addEventListener in the javascript below is being displayed always, even if the user does not click the button, the event is called and the alert is displayed. I would like to ensure the alert is only displayed when the button is actually clicked.

Any help that you can provide would be awesome.

Cheers Dre

var app = {
// Application Constructor
initialize: function() {
this.bindEvents();
},
bindEvents: function() {
document.addEventListener('deviceready', this.onDeviceReady, false);
},
// deviceready Event Handler
onDeviceReady: function() {
alert("PhoneGap is working in index.js onDeviceReady");
var buttonTwo = document.getElementById("btnPageTwo");

// the below event listener is fired always, even without the user clicking or performing any action the alert is displayed
buttonTwo.addEventListener('click', alert("Button Clicked"), false);
app.receivedEvent('deviceready');
},

// 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);
}
};

app.initialize();

You are using alert directly in add event. use function instead

buttonTwo.addEventListener('click',function(){ alert("Button Clicked");}, false);
