ng-click not fire function in controller - html

Question

The bug is very weird, I have been stucking here for hours just can find why my function in controller is fired.
Here is my HTML code:
<div class="col-md-9 clearfix" id="customer-account" ng-controller='ProfileController'>
<div class="box clearfix">
<div class="row">
<div class="col-sm-6">
<div class="form-group">
<label for="password_old">oldpassword</label>
<input type="password" class="form-control" id="password_old" ng-model="passwordold">
</div>
</div>
</div>
<div class="row">
<div class="col-sm-6">
<div class="form-group">
<label for="password_1">newpassword</label>
<input type="password" class="form-control" id="password_1" ng-model="passwordnew1">
</div>
</div>
<div class="col-sm-6">
<div class="form-group">
<label for="password_2">retype</label>
<input type="password" class="form-control" id="password_2"ng-model="passwordnew2">
</div>
</div>
<p>{{passwordnew2}}</p>
</div>
<!-- /.row -->
<div class="text-center">
<button type="submit" class="btn btn-primary">
<i class="fa fa-save" ng-click="changePwd(passwordold,passwordnew1,passwordnew2)"></i> save
</button>
</div>
<div class="text-center" >
<p>{{errorMessageChangepwd}}aaaa</p>
</div>
</div>
</div>
After I click the Button, which ng-click attribute as you can see, nothing happen.
Here is my controller code:
controller('ProfileController', ['$scope','UserFactory','SharedDataFactory',
function($scope,UserFactory,SharedDataFactory){
$scope.user = UserFactory.user;
$scope.passwordold;
$scope.errorMessageChangepwd='error';
$scope.showErrMsgChangepwd = false;
$scope.passwordnew1;
$scope.passwordnew2;
$scope.changePwd = function(passwordold,passwordnew1,passwordnew2){
console.log("aaaaaaaaaa");
if (passwordnew1!==passwordnew2){
$scope.showErrMsgChangepwd= true;
$scope.errorMessageChangepwd = 'error';
}else{
UserFactory.changePwd(passwordnew1)
.catch(function(err){
console.log(err.data);
}).then(function(response){
console.log(response);
});
}
};}]);
I called console.log("aaaaaaaaaa"); in the first line of my function, but after I click the button, nothing is shown on console.
And also
<div class="text-center" >
<p>{{errorMessageChangepwd}}aaaa</p>
</div>`
does not show error aaaa as expected but aaa on the browser.
what could be wrong?
Thanks.

You need to add ng-controller="ProfileController" in the top of your form.
Which looks like missing on your code.
