ZO_ObjectPool_CreateControl is simply a shortcut to CreateControlFromVirtual which abuses TemplateName as NamePrefix:

function ZO_ObjectPool_CreateControl(templateName, objectPool, parentControl)
    return CreateControlFromVirtual(templateName, parentControl, templateName, objectPool:GetNextControlId())
end

So this may better:

local button = CreateControlFromVirtual("NotebookIndex", notebook.toc.scrollChild, "ZO_DefaultTextButton", indexPool:GetNextControlId())

CreateControlFromVirtual just does:

local button = WINDOW_MANAGER:CreateControlFromVirtual("NotebookIndex" .. indexPool:GetNextControlId(), notebook.toc.scrollChild, "ZO_DefaultTextButton")

By the way: Is "NotebookIndex" really unique enough?
Another thing you should ask yourself is: Why using a pool instance and counting on your own with buttonCount?
If you want to chain controls in a loop you may change the whole construct to use a variable "lastControl" which remembers the previous button to anchor to.
Why recreating the control's names and look into the global instead of saving a reference to the "right" button in notebook.selectedpage.button
And what, if this button already exists?

Good luck
