Angularjs animate ngClick + ngShow with custom directive (mySlide)

I'm trying to get the same ultimate functionality as ng-click + ng-show, except that I want the show to slide in instead of suddenly appear by toggling display: block/none;. I've got the jQuery animate I need, and I've set up the ng-click. I've got 2 problems, but the second might be a result of the first:

Problem 1

ng-click does not change the value of aside_users. I saw SO#12202067 which seems to be a similar situation, but I don't understand how/why their custom directive works and the native ng-click doesn't.

I see the scope: { … } after restrict: 'A',, but that appears to make $scope values available within the newly-created DOM element (my elements already exist and show up just fine, but no triggers/events are happening).

infobox.html

<aside
  class="users"
  ng-include src="'views/users.html'"
  my-slide={"direction":"left","condition":"aside_users"}
></aside>

<i
  class="icon icon-user"
  ng-click="aside_users=!aside_users"
  ng-init="aside_users=false"
></i>

The above code is a $compile'd template and elsewhere within the template I print out the value of the $scope parameter aside_users (prints false).

Problem 2

my-slide doesn't seem to be initiated/triggered (the logging of 'elm: ', elm doesn't appear in Chrome's console). I verified that directives.js is linked in my index.html page.

EDIT I remembered to link directives.js in index.html, but I forgot to add it to the resources array in app.js.

Plunkr

P.S. I'm not sure if <aside attr={object}> is strictly valid, but legitimate browsers seem to accept it in test cases (didn't bother to check IE). My alternate plan is to use 2 attributes: <foo my-slide="direction" my-condition="boolean"></foo>
