So, if I understand this right:
- for every “container” control (e.g. section, obsgroup etc) - an onload() function will be called on mount of the control
- if “add-more” is allowed for the control, and if so clicked on form for a container control - the control.onload() function will be called for the newly added control.
- These events are fired only for the control thats being added - and will have no effect or any other event being fired for either the parent control or sibling controls.
