Uncaught TypeError: Cannot read property 'diagnostic' of undefined on Phonegap - cordova-plugins

Question

In my Phonegap project the Diagnostic plugin gives the following error!
Uncaught TypeError: Can not read property 'diagnostic' of undefined
I have already virified the versions, uninstalled and installed the plugin. And this always happens, I've even been isolated from other plugins!
var structureApp = {
initialize: function(){
this.bindEvents();
},
bindEvents: function() {
document.addEventListener('deviceready', this.onDeviceReady, false);
document.addEventListener("deviceRegistered", this.successDeviceRegistered, false);
},
onDeviceReady: function() {
structureApp.mount();
navigator.geolocation.getCurrentPosition(
structureApp.geoLocate,
structureApp.geoErro,
{enableHighAccuracy:true, maximumAge:30000, timeout:27000}
);
.structureApp.getPosition();
},
mount: function() {
structureApp.logoutNotification();
},
geoLocate: function(position){
var lat=position.coords.latitude;
var lon=position.coords.longitude;
localStorage.setItem('lat',lat);
localStorage.setItem('lon',lon);
$("#latitude").html("Sua Latidute:" + lat);
$("#longitude").html("Sua Longitude:" + lon);
},
geoErro: function (e){
alert("Houve um erro:" + e.message);
},
getPosition: function (){
cordova.plugins.diagnostic.isLocationAuthorized(function(enabled){
if(!enabled){
navigator.diagnostic.requestLocationAuthorization(function(status){
navigator.geolocation.getCurrentPosition(function(position){
alert(position.coords.latitude, position.coords.longitude);
startSplash();
}, function(error){
alert("Something went wrong while retrieving your position. " + error.message);
},
{
maximumAge:6000,
timeout:5000,
enableHighAccuracy: true
});
},function(error){
alert(error.message);
});
}
},function(error){
alert("The following error occurred: " + error.message);
});
}
};
$(function(){ structureApp.initialize(); });
My config.xml looks like this:
<?xml version='1.0' encoding='utf-8'?>
