Angular: Building a directive and remove attribute from root element - templates

Question

Is it possible to do something like this:
<field:text id="foo" label="Foo Label" model="model.foo" placeholder="foo" />
which would be compiled to:
<div class="control-group">
<label class="control-label" for="foo">Foo Label</label>
<div class="controls">
<input type="text" id="foo" placeholder="foo" ng-model="model.foo">
</div>
</div>
I tried to make a example, but Plunker wouldn't let me save my example... uploaded it to dropbox: https://dl.dropbox.com/u/2862814/plunk.zip
The example breaks with stuff like ng-change. This is due the compilation of the ng-change directive. I tried it with a high priority to the fieldText directive, but doesn't fix it.

Answer 1

You were pretty close with in your example, but you have to put ng-change on the input-field in the template. Your old code:
<field:text ng-change="updateHidden()" ...
Change this to
<field:text change="updateHidden()" ...
and in the directive (see http://docs.angularjs.org/guide/directive - & or &attr - provides a way to execute an expression in the context of the parent scope.)
{scope:{change:'&' ...
and finally the directive template
<input ng-change="change()" ...
Here is a modiefied and working plunkr: http://plnkr.co/edit/QmQjGQQBRtDmkCka0dul?p=preview
<field:text id="too" label="Too" model="model.too" placeholder="too" change="updateHidden()"></field:text>
<script type="text/ng-template" id="/tpl.html">
<div class="control-group">
<label class="control-label" for="{{id}}">{{label}}</label>
<div class="controls">
<input ng-change="change()" type="text" id="{{id}}" placeholder="{{placeholder}}"
ng-model="model">
</div>
</div>
</script>
directive('fieldText',function(){
return {
restrict:'E',
templateUrl:'/tpl.html',
scope:{change:'&',id:'#',model:'=',placeholder:'#',label:'#'}
}
})
