How do I change HeaderText in Javascript?

[Dan]

I am working a simple scenario, when the user changes a control, I would like to conditionally change a couple of Column HeaderText properties in a RadGrid.  I can get the HeaderText this way:

alert($find('<%=myGrid.ClientID %>').get_masterTableView().getColumnByUniqueName('Estimated_Qty').get_element().innerHTML);

But if I change the value like this:

$find('<%=myGrid.ClientID %>').get_masterTableView().getColumnByUniqueName('Estimated_Qty').get_element().innerHTML = 'Billed Qty';

The change does not show in the grid.

Is there another way of doing this?  a set_headerText() or something similar?  I can't find anything in the documentation.

Thanks!

Hello Dan,

var tableView = $find("<%= RadGrid1.ClientID %>").get_masterTableView();
               tableView.get_columns()[0]._element.innerText = "jayesh";
