    copied!<p>I have this as my bootstrapped data, which I push to the model when nothing is retrieved from the DB:</p> <pre><code>var liveaudience = { triggers : [ { 'trigger_id': 'vocal_stomp', 'duration': 1000, 'color': '#F23000', 'sound': 'A#' }, { 'trigger_id': 'guitar_stomp', 'duration': 600, 'color': '#CC0234', 'sound': 'Cmaj' }, { 'trigger_id': 'drum_pad', 'duration': 1200, 'color': '#CF2451', 'sound': 'Emin' } ] }; </code></pre> <p>I have this one route, which does this and then renders these three bootstrapped elements on the template:</p> <pre><code>get('/:triggerId?', function(page, model, params){ var triggers = model.get('liveaudience.triggers'); if(typeof triggers === 'undefined'){ // bootstrap triggers model.push('liveaudience.triggers', liveaudience.triggers); } model.subscribe("liveaudience.triggers", function(err, scopedModels){ page.render({'triggers': scopedModels.get()[0]}); }); }); </code></pre> <p>and then here is the template:</p> <pre><code>&lt;ul id="triggers"&gt; {{#each triggers}} &lt;li data-id="{{id}}" class="trigger" style="background-color:{{color}};"&gt; &lt;span class="trigger-label"&gt;{{trigger_id}}&lt;/span&gt; &lt;a x-bind="click:removeTrigger" class="remove-trigger"&gt;x&lt;/a&gt; &lt;/li&gt; {{/}} &lt;/ul&gt; </code></pre> <p>Everything shows up, but {{id}} returns a function, and I'd like it to be a uniquely assigned <a href="http://derbyjs.com/#guids" rel="nofollow">GUID</a>. The main issue is that I don't know how to get &amp; remove this element from the DOM when clicking and firing the <code>removeTrigger</code> handler. Looking at examples, I've seen this within the handler:</p> <p><code>model.at(e.target).remove();</code></p> <p>but that doesn't work.</p> <p>Any ideas?!</p>
