Example for fx-send within a Repeat

[RibeyeOnTheBone]

I have a button on the rows of a table which needs to trigger an fx-submission

            <button>
              Recalculate
              <fx-send event="click" submission="recalc"></fx-send>
            </button>

I cant get my use case to work, which is to send the entire instance to the back end, get back a value to replace the value in one of the columns on the calling table row.

Is there an example somewhere? I cant find one.

Thanks

targetref should help as in this demo - https://jinntec.github.io/Fore/demo/targetref.html

<fx-submission id="submission" 
    ref="instance('payload')" 
    method="post" 
    url="#echo" 
    replace="instance" 
    instance="result" 
    targetref="instance('result')/result/row[index('r-rows')]">
</fx-submission>

targetref should also work on the instance that's been sent. Of course you need to make sure somehow that you know the position to update index('r-rows') being just an example using a repeats' index.
