i trying set values input type="text" in ngdialog server, find populating dummy values not make values show "in dialog" - in if set values in form using javascript see them on textbox in view. however, not seem work ngdialog, - inspite of binding textbox ng-model , name attributes. question is, ngdialog setting text using $modelvalue not show values in text box?

for e.g -  $scope.myform.mytextbox.$modelvalue = "xyz" not show  form in html similar shown below -  <div class="container-fluid" ng-controller="addusercontroller">      <div class="text-center">         <label class="sub-header">add user</label>     </div>      <form action="...r" method="post" name="myform">         <div>             <div>                 <input type="text" class="form-control" ng-model="mytextbox"                     name="mytextbox" required                      ng-minlength = "1" ng-maxlength="50"                     placeholder="enter first name" bs-typeahead>                                 </div>          </div>        </form>     </div>
