Some scope watch may caused angular dirty check goes wrong.

[Woodu]

In Line 481:

 _bindEvents: function () {
                    var that = this;
                    this._scope.$watch('[ngc.alignMiddle, ngc.offsetTop, ngc.offsetBottom]', function () {
                        that.setDialogCenter('bindEvents');
                    });

due to angular offical document (https://docs.angularjs.org/error/$rootScope/infdig ),those code may caused dirty check error.
I modified to this.

_bindEvents: function () {
          var that = this;
          var boxSets = [this._scope.ngc.alignMiddle, this._scope.ngc.offsetTop, this._scope.ngc.offsetBottom];
          this._scope.$watch(boxSets, function () {
            that.setDialogCenter('bindEvents');
          });

same error here, woodu's solution works

from v1.1.0
ngConfirm wont use scope for internal operations,
this caused problems in memory leaks and circular references.

previous code is completely removed.
