Cannot change checkbox in Sidebar

[tom-lp-at]

Bug Report

if i use a checkbox in a (left) sidebar, it´s shown with it´s initial state, but cannot clicked to change. i reduced the complete code to the smallest possible, but the behaviour is always the same

Steps to reproduce

<div class="ui checkbox">
	<input type="checkbox"   id="check" name="check" checked="checked">
	<label for="check"></label>
</div>

Expected result

change the state of the checkbox

Actual result

checkbox stays in it's initial state

Version

2.8.4 (4. March 2020)

I try different ways and reduce the whole code. Buttons/Icons/img with onclick in the left sidebar are working and the events are fired, but not for the checkbox (i remove the onchange above).
i try it with onclick and the events fires up, but the checkbox didn´t change his state...
if the checkbox is outside of the sidebar (for example in a content-div) the checkbox change his state as expected....
(i try it without for="check" too, also without name...)

Initialize your checkboxes by $('.ui.checkbox').checkbox()

oh my God - i am so sorry to make (so stupid) noise :(
Thank you to bring me back to the right way...
It's - in the start - irritating to "initialize" basic html things like checkboxes :)
