no feedback icons

[vicary]

I tried to add it back, but I have no idea when to trigger form validation on date change.

Here is the template code I edited, added feedback span and decorator class bindings. But it always shows glyphicon-ok.

angular.module("schemaForm").run(["$templateCache", function($templateCache) {$templateCache.put("directives/decorators/bootstrap/datepicker/datepicker.html","<div class=\"form-group {{form.htmlClass}}\" ng-class=\"{'has-error': form.disableErrorState !== true && hasError(), 'has-success': form.disableSuccessState !== true && hasSuccess(), 'has-feedback': form.feedback !== false }\">\n  <label class=\"control-label\" ng-show=\"showTitle()\">{{form.title}}</label>\n  <div ng-class=\"{\'input-group\': (form.fieldAddonLeft || form.fieldAddonRight)}\">\n    <span ng-if=\"form.fieldAddonLeft\"\n          class=\"input-group-addon\"\n          ng-bind-html=\"form.fieldAddonLeft\"></span>\n    <input ng-show=\"form.key\"\n           style=\"background-color: white\"\n           type=\"text\"\n           class=\"form-control {{form.fieldHtmlClass}}\"\n           schema-validate=\"form\"\n           ng-model=\"$$value$$\"\n           ng-disabled=\"form.readonly\"\n           pick-a-date=\"form.pickadate\"\n           min-date=\"form.minDate\"\n           max-date=\"form.maxDate\"\n           name=\"{{form.key.slice(-1)[0]}}\"\n           format=\"form.format\" />\n    <span ng-if=\"form.fieldAddonRight\"\n          class=\"input-group-addon\"\n          ng-bind-html=\"form.fieldAddonRight\"></span>\n  </div>\n  <span ng-if=\"form.feedback !== false\" class=\"form-control-feedback\" ng-class=\"evalInScope(form.feedback) || { 'glyphicon': true, 'glyphicon-ok': hasSuccess(), 'glyphicon-remove': hasError() }\"></span>\n  <span class=\"help-block\">{{ (hasError() && errorMessage(schemaError())) || form.description}}</span>\n</div>\n");}]);

How should I change the code in pickADate directive?
