Alex I Badly Needs load some checkboxes with unchecked values

I am using a grid to which i would like to load the unchecked checkboxes .
With some values in the same column i am using the following test code

var respData = [
[ "Test1", "Test2" ,"Test3","Test4","Test5","Test6","Test7"]
];

var respHeaders = ["col1", "Col2", "Col3", "Col4", "Col5","Col6","Col7"];
var obj = new AW.UI.Grid;
obj.setId("respGrid");
obj.setCellText(respData);

var obj = new AW.Templates.Checkbox;
obj.setControlValue(false);
obj.setCellTemplate(obj, 0);

okay small correction chechbox var is objChk
ie var objeChk = new AW.Templates.Checkbox;

did any body tried this ?
