<input type="text" value="{{codes[0].code}}" ng-click="newNumber(0)" />
<input type="text" value="{{codes[1].code}}" ng-click="newNumber({{codes[1].id}})" />
The first ng-click event fires in my controller just fine but the second one does nothing.
I tried concat'ing as well ... is there some other way I should do this?
The value of ng-click is already evaluated as an angular expression. As such, you don't need the {{ }}. Read http://docs.angularjs.org/guide/expression for more information. Take a look at the second example, it will help clarify this.
Also, ng-model should be used for data-binding. For example, take a look at this jsfiddle: http://jsfiddle.net/bCpW9/8/ and the notes below.
<li ng-repeat="code in codes">
This loops through the codes collection which was defined in the controller. It creates a <li> for each element in the codes collection.
<input ng-model="codes[$index].code" />
Inside each <li>, an <input> for the current code is created. Each input is bound to it's corresponding element in the codes array by setting ng-model to it. For instance, type a new code into the first input field. It automatically updates the corresponding code model with what you typed, as you can see to the right.
I hope that helps.

ng-click="newNumber(codes[1].id)". Why you are usingvalueinstead ofng-model?
