Thanks, and I apologize: in trying to clarify my question, I oversimplified my illustration and skewed your answer to it. The [JSBin](https://jsbin.com/levunun/edit?html,output) I furnished contains only one `` element, but the model I’m attempting to construct needs 16 such elements, each with slightly different attributes (innerHTML and background-color: it’s a color-picker). I’m hoping to listen for a `click` event on each `` in order to use the whole set of ``s as a 16-position “switch” to control other parts of the web app. And I want to use stache to change a clicked element’s style and distinguish it visually. Currently I define the set of 16 ``s as a single string with a JavaScript `for()` loop, then use that string as my (parent) `Component.extend()`'s `view:` definition. This works fine, but because I’m coding it at the **_parent level_** , any `event:` defined in this `Component.extend()` affects **_all_** ``s at once (the problem you helped me avoid in [How to limit event outcome to element of origin](https://forums.bitovi.com/t/how-to-limit-event-outcome-to-element-of-origin/919?u=code-read)). This problem of “overgeneralization” led me to define a separate `Component.extend()` specifically for ``, but without a `view:`. This approach **_almost_** works: its ViewModel traps clicks on individual `` elements and configures stache content in their specific innerHTMLs, but does not configure their `class` (or other “outerHTML” content) via stache (as demonstrated in [https://jsbin.com/levunun/edit?html,output](https://jsbin.com/levunun/edit?html,output)). Conceptually, I’m attempting to 1) build a series of similar HTML elements in a loop; and 2) listen and respond to changes and/or events occurring on each one separately. I’m looking for the simplest and most “ideomatic” way of doing so via CanJS. --- _[View the full topic](https://forums.bitovi.com/t/communication-between-sibling-viewmodels/927)._
