Pass AMP state in action xhr

i am working on amp-form. in action-xhr i have to pass a amp state with url.

leadProfileId is amp state.

<form method="post" action-xhr='@currentHostUrl/api/stocks/leadProfileId/negotiate' id="submitOfferForm" target="_top"
                  on="submit-success: AMP.setState({ selectedOffer : null })">
                <input hidden name="priceOffered" [value]="selectedOffer">
                <input hidden name="mobileNumber" [value]="mobileNo">
            </form>

i have tried following approaches but it's not working.

'@currentHostUrl/api/stocks/{{leadProfileId}}/negotiate'
"'@currentHostUrl/api/stocks/'leadProfileId'/negotiate'"

Solution

Jay Gray correctly asked you about where you have the amp-state tag? It is unclear where you write data using AMP.setState({ anyData: 'anyValue'})

Unfortunately, I don't know how to make the action-xhr attribute bind from amp-state. See this topic: https://github.com/ampproject/amphtml/issues/11222

When we don't know how to bind something in AMP, the amp-list component usually helps us out. Solution:
