Knockout JS removes jQuery change event
I don't know if it is specific to Magento 2 but an already set up HTML node with jQuery change event attached to it will lose its change event when run inside a knockout component with attached VM (view model).
Situation in Magento:
I moved the product options wrapper via a layout xml into a custom block
<referenceBlock name="product.info.form.options">
// Custom block definition
<move element="product.info.options.wrapper" destination="custom.block" />
</referenceBlock>
That works without any issues!
Now when wrapping around this moved block a knockout model with Magentos custom "scope" binding, all applied onChange events are getting removed - which means in this case the configurable option select boxes staying disabled.
The change events are getting applied here
$(element).on('change', this, this._configure);
.. which also seems right for me on how to add an event.
So in my template file I do the following to wrap my knockout component (with attached VM) around this html snippet:
<div class="tab-content" data-step="1" data-bind="scope:'times'">
<?php echo $block->getChildHtml('product_options_wrapper'); ?>
</div>
With change event on product wrapper dropdowns:
Withoout change event on dropdowns when nested inside Knockout component:
Anybody knows if this a thing between KnockoutJS and jQuery or if this has something to do with Magento?

I'm not sure why the on change event is removed (conflict maybe?), but you can do something similar with Knockout itself:
<select data-bind="event:{ change: yourFunction}">
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
Helpful links
This looks better practice to me rather than mixing KO and jQuery.
There is a Fiddle with a none Magento example here.
This answer is also pretty helpful.

The thing is, I want to use the configurable attribute filter options incl. the logic Magento already ships with. So the dependency between multiple options getting enabled/disabled - that is why I moved the complete wrapper and why I cannot apply my own event. Hope that was clear.. oO

If it has to be done with the default functionality then I have no idea sorry :(
