You are initializing the ListView for second time instead of getting the client object. You should get the object like follows and use the setDataSource method.
e.g.
var lvTravelerImageData = new kendo.data.DataSource({ data: data.TravelerImages });
//alert(data.TravelerImages[0]) // works great
$('#lvTravelerImages').data("kendoListView").setDataSource(lvTravelerImageData);
lvTravelerImageData.read();
