Cannot re-use checkbox functions in ReactJS

I have a mapping function which shows JSON values into checkboxes, each checkbox triggers another 2 checkboxes, the JSON i am using have a min/max value which i made a function for to set min/max for checkbox selections in each section, both features works fine. The problem is however, that once the parent checkbox is clicked and it expands to show 2 functional checkboxes, then i redo the process where i click it to shrink it and click it again to expand it, the children checkboxes stops being clickable.

The checkbox values are passed as props from Checkbox.js to Itemlist.js where the fetch/map happens. Would Appreciate it if anyone can explain or demonstrate how this can be achieved.
