Hey Eric,
So far in my branch I have Firebase.key(), limitToFirst(), limitToLast(),
child_moved working. I have orderByChild, orderByKey, and orderByKey
partially working.
When I use my firebase-element:
<firebase-element id="dinosaurOrderByChild" on-data-change=
"{{dinosaurOrderByChildDataChange}}" data="{{dinosaurOrderByChildData}}"
keys="{{dinosaurOrderByChildKeys}}" orderByChild="order" location=
"https://dinosaur-facts.firebaseio.com/"; log></firebase-element>
The console shows that the child-addd have been sorted ok, but the data
stored in dinosaurOrderByChildData is not sorted.
Console log messages:
child-added lambeosaurus firebase-element.html:420
child-added stegosaurus firebase-element.html:420
child-added triceratops firebase-element.html:420
child-added pterodactyl firebase-element.html:420
child-added bruhathkayosaurus firebase-element.html:420
child-added linhenykus firebase-element.html:420
acquired value https://dinosaur-facts.firebaseio.com/
firebase-element.html:321
And the object stored in dinosaurOrderByChildData is not sorted.
{bruhathkayosaurus: Object, lambeosaurus: Object, linhenykus: Object,
pterodactyl: Object, stegosaurus: Object…}
*Do you have and idea why this is happening?*

Requery function
```
requery: function() {
// shut-down previous observers (if any)
this.closeQuery();
this.closeObserver();
// construct new query
var query = this.ref;
if (query) {
if (this.start && !this.orderByKey) {
console.log("requery: startAt", this.start);
query = query.startAt(this.start);
}
if (this.end) {
query = query.endAt(this.end);
}
if (this.limit > 0) {
query = query.limit(this.limit);
}
if (this.limitToFirst > 0) {
query = query.limitToFirst(this.limitToFirst);
}
if (this.limitToLast > 0) {
query = query.limitToLast(this.limitToLast);
}
*if (this.orderByChild) { console.log("requery: orderByChild",
this.orderByChild, this.ref); query =
query.orderByChild(this.orderByChild); }*
if (this.orderByKey) {
if (this.start) {
query = query.orderByKey().startAt(this.start);
} else {
query = query.orderByKey();
}
// console.log("requery: orderByKey", query);
}
if (this.orderByPriority) {
console.log("requery: orderByPriority", this.ref);
query = query.orderByPriority();
}
this.query = query;
// console.log("requery: query", this.query)
}
},
```
