AngularJS expression throwing a Syntax error in ng-click

Ok, I am working on a comment section of a website where users can leave comment on the original post or any subsequent post. To accomplish this rendering in angular.js, I had some fun with recursion.

<script type="text/ng-template"  id="renderer.html">
   {{comment.userName+' - '+comment.commentText}}
   <br/><button class="standardButton">respond</button>

   <ul>
       <li ng-repeat="comment in comment.childComments | orderBy:'commentId'" ng-include="'renderer.html'"></li>
   </ul>
</script>

<ul>
    <li data-ng-repeat="comment in comments" data-ng-include="'renderer.html'"></li>
</ul>

This by itself works perfectly. However, I need to be able to see data about which button was clicked. I updated my code to this:

<script type="text/ng-template"  id="renderer.html">
{{comment.userName+' - '+comment.commentText}}
<br/><button class="standardButton" ng-click='alertMe({{comment.userName}})'>respond</button>

<ul>
    <li ng-repeat="comment in comment.childComments | orderBy:'commentId'" ng-include="'renderer.html'"></li>
</ul>

Please notice the addition of the ng-click. The alertMe method was successfully tested in the controller with plain strings. It only breaks when using angular expressions.

I get the following error in the console for every comment loaded:

> Error: [$parse:syntax]
> http://errors.angularjs.org/1.2.15/$parse/syntax?p0=comment.userName&p1=is%20unexpected%2C%20expecting%20%5B%3A%5D&p2=11&p3=alertMe(%7B%7Bcomment.userName%7D%7D)&p4=comment.userName%7D%7D)

> class="standardButton" ng-click="alertMe({{comment.userName}})">

The angular site has this to say:

Error: $parse:syntax Syntax Error Syntax Error: Token 'comment.userName' is at column {2} of the expression [{3}] starting at [{4}].

Does anybody know what is causing this error? Any and all information is greatly appreciated.

You don't need brackets in ng-click, as it expects an expression, not a template. Change the offending line to:

<br/><button class="standardButton" ng-click='alertMe(comment.userName)'>respond</button>
