This pattern of using a callback will require a closure, something like this:
<pre class="brush:js;">
var myUiCallback = function (results) {
this.document = document; // pull in a reference to the current chrome or content
let resultsList = this.document.getElementById("history-results");
for (let item in results){
let node = this.document.createElement("li");
node.innerHTML = results.title;
}
}
</pre>
