when i right click on the cell i want to get the clicked cell column name.

can any one help me how to do this task.

using this code i am able to getting the cell index.but i can't able to getting the column header text.

function RowContextMenu(sender, eventArgs)
{
        if (eventArgs.get_tableView().get_name() == "PRRequests")
                {
                    if (eventArgs.get_domEvent().target.tagName == "TD")
                    {
                    alert(eventArgs.get_domEvent().target.cellIndex);
                    //alert(eventArgs.get_gridColumn().get_uniqueName());
                    }
                }
}

 
"PRReuests" is the Detail Table Name.
