Phonegap image file is not saved permanently iOS - ios

Question

Hi i'm trying to capture a photo and save it permanently to the filesystem. Taking the photo works so far, but it seems it doesn't save it permanently to the filesystem. After i restart the app, the pictures are gone.
The path of the picture is saved to my WebSQL Database (which works without problems)
Here is the part of my code:
function capturePhoto() {
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50,
destinationType: destinationType.FILE_URI, saveToPhotoAlbum: true });
}
function onFail(message) {
console.log('Failed because: ' + message);
}
function onPhotoDataSuccess(imageURI) {
movePic(imageURI);
}
function movePic(file){
window.resolveLocalFileSystemURI(file, resolveOnSuccess, resOnError);
}
//Callback function when the file system uri has been resolved
function resolveOnSuccess(entry){
var d = new Date();
var n = d.getTime();
//new file name
var newFileName = n + ".jpg";
var myFolderApp = "LeadAppPhotos";
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fileSys) {
//The folder is created if doesn't exist
fileSys.root.getDirectory( myFolderApp,
{create:true, exclusive: false},
function(directory) {
entry.moveTo(directory, newFileName, successMove, resOnError);
},
resOnError);
},
resOnError);
}
//Callback function when the file has been moved successfully
function successMove(entry) {
//put the path url in a div so i can save it later to my websql database
$('#hidden_photo').val(entry.fullPath);
}
function resOnError(error) {
alert(error.code);
}
What's my mistake?
