Textbox template : Error !!!

from http://www.activewidgets.com/javascript.forum.1394.35/textbox-template-edit-on-double.html
very good job,but I've some problem??

1. when I edit first cell ,all of data(all cell) become that data in edit box
I think from this code setItemproperty() make all data to edit item

function switchToTextMode(){ 
        var value =    editor.element().value; 
        [b]template.setItemProperty("text", value); [/b]
        template.refresh(); 
        template = null; 
    }

2. Can I send data to server (asp,php) : array of data??

Thank you for your advice
Thanl Alex for all of code, very impressed me ;)
