angularjs - Dynamically add directive on an element that doesnt exist yet -

-

i'm using this plugin bootstrap dropdown angularjs. issue i'm having code want looks to

<ol class="nya-bs-select" ng-model="city" name="city" required>                  <li nya-bs-option="city in subcities ">                      <a>{{ city.name }}</a>                 </li>             </ol>

which generates like

    <ol ng-model="city" class="nya-bs-select ng-pristine ng-untouched btn-group ng-invalid ng-invalid-required">                      <button type="button" class="btn btn-default dropdown-toggle"><span class="pull-left filter-option">- select -</span>&nbsp;<span class="caret"></span></button>       <div class="dropdown-menu open">           <ul class="dropdown-menu inner">             <li><a>- select -</a></li>             <li nya-bs-option="city in subcities" class="ng-scope nya-bs-option">                         <a tabindex="0" class="ng-binding">cityname</a>             </li>           </ul>       </div> </ol>

as can see adds "button" element child of <ol>. how can "listen" "nyabsselect" directive when creates <button> element, want add ng-disabled directive button's attribute?

you can add 1 more directive in same element nya-bs-select. directive can find button , add attribute. want add directive attribute might have $compile of button after adding attribute. can modify priority directive executes after plugin directive. have not looked plugin. guess modify plugin add 1 more attribute , ng disabled button , bind both.

c# - TransactionScope not rolling back although no complete() is called -

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
