angularjs - Angular datepaicker works in minial project, not in full-blown -

i have bare bones, minimalistic app, includes in html of view

<input type="text" class="form-control" uib-datepicker-popup="{{format}}" ng-model="dt"    is-open="popup1.opened" min-date="mindate" max-date="maxdate"   datepicker-options="dateoptions" date-disabled="disabled(date, mode)"   ng-required="true" close-text="close"    alt-input-formats="altinputformats" />  <span class="input-group-btn">    <button type="button" class="btn btn-default" ng-click="open1()">         <i class="glyphicon glyphicon-calendar"></i></button> </span> 

and in controller

$scope.open1 = function() {    $scope.popup1.opened=true; }  $scope.popup1 ={'opened': false} $scope.dt = new date(); 

when click calendar icon in demo project, calendar pops open, not in full-blown project, when copy/paste code ($scope.popup1.opened change false true when clicked).

the full blown project large post - advice?

[update] help. 1 point notice code works in minmial project, not in full-blown project, regardless of suggested duplicate question.

however, have taken on board suggested duplicate an, alas, not help.

   $scope.swallowclick = function($event)    {       if ($event.cancelable)            $event.preventdefault();          $event.stoppropagation();           return false;   // don't handle event further    }      $scope.open1 = function($event)    {         $scope.swallowclick($event);         $scope.popup1.opened=true;         return false;   // don't handle event further    } 

have seen question , accepted answer? ui.bootstrap.datepicker is-open not working button

try passing $event ng-click handler, this...

<span class="input-group-btn">    <button type="button" class="btn btn-default" ng-click="open1($event)">         <i class="glyphicon glyphicon-calendar"></i></button> </span> 

and in javascript, this...

$scope.open1 = function($event) {     $event.preventdefault();     $event.stoppropagation();     $scope.popup1.opened=true; }  $scope.popup1 ={'opened': false} $scope.dt = new date();
