The simplest thing that comes to mind is to use a directive controller in
your label directive and to place the input inside the label.
<label my-label>
<input my-input ng-model="whatevs">
</label>
.directive('myLabel', function() {
return {
controller: function(el, attr) {
...
}
}
});
.directive('myInput', function() {
return {
require: '^myLabel'
link: function(scope, el, attr, myLabelCtrl) {
...
}
}
});
