deleteSelectedItems() problem

[Nikola]

Hi

I have a problem with method deleteSelectedItems()

I have a method in javascript

function RemoveItems() {
        var masterTable = $find("<%= gvArticlesEdit.ClientID %>");
        var selectedItems = masterTable.get_selectedItems();
        masterTable.deleteSelectedItems();

    }

var selectedItems is for testing to see how radGrid get selectedItems and it is working fine. But, this line:
masterTable.deleteSelectedItems(); 
delete all objects in radGrid...

If something help's , this is part of code for binding object in that grid, and that's work fine

var item = new Object();

        item.Name = name;
        item.Measure = unitMeasure;
        item.Items = items;

        allItems.push(item);
        var tableView = $find(gArticlesEditID).get_masterTableView();
        tableView.set_dataSource(allItems);
        tableView.dataBind();
