when one click works and the other not - html

Question

I got the problem that i got 2 ng-clicks but only one works. when I reload the page always only one button works the other not. for this i use angularjs, HTML and Css.
the first click:
<img class="cClickable" ng-click="addPassword()" src="plus.svg">
AngularJS:
$scope.addPassword = function() {
var newPassword = {
Id: null,
Name: '',
Passwort: '',
Beschreibung: '',
Category: []
}
$scope.editPassword(newPassword);
$scope.titlePopup = "Neues Passwort hinzufügen";
}
$scope.editPassword = function(password) {
$scope.currentPassword = angular.copy(password);
$scope.isShownEdit = true;
$scope.titlePopup = "Passwort bearbeiten";
}
the second button:
<img class="cClickable cTableImgedit" ng-click="editPassword(item)" src="pencil.svg">
when i click the button a popup is in the front.
the images are existing.
this is the popup.
<div class="backgroundOverlay cShow" ng-show="isShownEdit">
<div class="dropDown positionPopUp inpuBlock" id="add">
<div class="inputBlock">
<h1 class="popupTitle">{{titlePopup}}</h1>
<div>
<div class="cClearFloat cInputSpace">
<input placeholder="Name" ng-model="currentPassword.Name">
</div>
<div class="cClearFloat cInputSpace">
<input placeholder="Passwort" ng-model="currentPassword.Passwort">
</div>
<div class="cClearFloat cInputSpace">
<input placeholder="Beschreibung" ng-model="currentPassword.Beschreibung">
</div>
<div class="cClearFloat cInputSpace">
<div class="divSmall">
<label class="inputDropdownPlaceholder">Kategorien</label>
<div class="divOptions" ng-repeat="item in categories">
<label class="labelDropDown"><input type="checkbox" class="inputDropDown" ng-model="item.isChecked" ng-checked="checkedCategory(item)" ng-init="item.isChecked = checkedCategory(item)" ng-change="changedCategory(item)">{{item.Label}}</label><br>
</div>
</div>
<div class="cClearFloat cButtons">
<button class="cButtonSpeichern" ng-click="showAlertPassword()">Speichern</button>
<button class="cButtonAbbrechen" ng-click="isShownEdit= false">Abbrechen</button>
</div>
</div>
</div>
</div>
</div>
</div>
when i click on the images the popup comes into the front.
