When using byte_size_f or counter_f in volume-templates for dynamically adding volumes for compute-resources in host creation, the buttons of these elements do not work.

The reason for this is that a template-volume is created and the spinners are initialized.
When a new volume is created on the GUI, the template-volume form is copied as html-string and added to the page, which loses the event-handling.
Calling tfm.numFields.initAll() does not fix it.
