Adding New ListItem via Button Test in List View

I gain some experience in understanding the new Titanium Alloy version 3.2.x that has an MVC structure and appeared fairly easy. Now, since I mastered making listview and switching window views, I'm trying to make a button functionality that allows you to add 1 new item. I create a var for list section and took the value from list section ID so that I could manipulate and test it for on item click to check item number. By using the list section variable, now, I'm making an on-click button function for adding 1 new item.

var args = arguments[0] || {};
 
//----------[ Variables ]----------
 
var section = $.location_section; // --> ID of the List Section tag.
var list = $.location_list_view;
$.location_list_view.allowsSelection = true; // --> For iOS.
 
 
 
 
 
//----------[ Button Click Event Listeners ]----------
 
function itemClick(e) {
    // $.location_list_view.sections[e.sectionIndex];
    // alert("List Item no. " + section.getItemAt(e.itemIndex));
    // var win = Alloy.createController('geo_fence_view');
    // win.getView().open();
    section.getItemAt(e.itemIndex);
    alert("List Item no. " + e.itemIndex);
}
 
function breakButton(e) {
    // var win = Alloy.createController('break_menu_view');
    // win.getView().open();
    // section.setItems($.location_list_view.getTemplates().);  
    var tmp = {
        properties: {
            template: "location_template",
            class: "location_item",
            location: {
                text: "RESERVE Y"
            }
        }
    };
 
    section.items = tmp;
    list.setSections(section);x 
    // list = Titanium.UI.createListView(section);
}

I tried cleaning it, running it, testing it onto an Android emulator powered by Genymotion and when I tried testing the button for adding 1 new item (temporarily named "BREAK"), it didn't add new list item. Is there a way or something that I could fix this bug by something like updating after adding 1 new item? Please help.
