Directive to use the value of the DOM element as the default for an ngModel instead of having to bootstrap from the controller.

ng_use_default.js.coffee

@app.directive 'ngUseDefault', ->
  restrict: 'A'
  controller: ['$scope', '$element', '$attrs', '$parse', ($scope, $element, $attrs, $parse) ->
    initialValue = $element.val()
    getter = $parse($attrs.ngModel)
    setter = getter.assign
    setter($scope, initialValue)
