Attaching JavaScript Events With Server Side Binding Code

Recently, I had to send the row index of the GridView row to a JavaScript function. The row index can be accessed using Container.DataItemIndex but I was having trouble with the commas and quotes stuff. So, I just used a server side method to generate a JavaScript method and return to the HTML side.
I still think the call to AttachFunction is not a good idea and this should be handled on the client side. Any refactorings?

<ItemTemplate>
<asp:TextBox ID="txtCategoryName" onchange='<%# AttachFunction(Container.DataItemIndex ) %>' runat="server" Text='<%# Eval("CategoryName") %>' />
</ItemTemplate>
protected string AttachFunction(int rowIndex)
{
string function = "saveRowIndex(";
return function + rowIndex + ")";
}
