问题
I have developed an AMP site where I have three radio buttons.
- show all
- show only favourite
- clear all
when i will click on clear all button it will show a lightbox. On that lightbox I have two buttons.
- ok
- Cancel
when user click on cancel from the lightbox the show all radio input will be checked. I have implemented it with amp-state variable change. For the very first time when i click on cancel it checked properly in show all radio input but after that if I have click on clear radio input and then cancel button again it does not checked again show all radio input.
Here i have added a sample code in codepen

Well, at last, I found the solution to this problem from amp-team. I am posting that answer so that if anyone faces the same problem they can solve it easily
<div class="favorite-content-filter">
<label>
<input name="filter" value="show_all" type="radio" role="button" tabindex="0"
on="change:AMP.setState({partnerLogo:{chkRadio : 'show_all'}})" checked
[checked]="partnerLogo.chkRadio == 'show_all' ? checked : '' ">
show all
</label>
<label>
<input name="filter" value="show_favorite" type="radio" role="button" tabindex="0"
on="change:AMP.setState({partnerLogo:{chkRadio : 'show_all'}})"
[checked]="partnerLogo.chkRadio == 'show_fav' ? checked : '' ">
show only favorites
</label>

<div class="lightbox-btn-grup">

</div>
</amp-lightbox>
<input

tabindex="0" on="change:favorite-lightbox, AMP.setState({partnerLogo:{chkRadio : ''}})"
[checked]="partnerLogo.chkRadio != show_all ? checked : '' "> Clear All
</label>
</div>
I just need to set the partnerLogo.chkRadio to something else when lightbox opens. Otherwise, the state would be out of sync with selected radio.
