AngularJS1 : ng-blur inside the ng-if - asp.net

Question

I'm trying to use ng-blur. Below is my HTML code:
<div ng-if="CurrentStage==='SaveQuery'">
<div class="col-sm-12">
<div class="form-group row">
<label class="col-sm-3 control-label text-right">Query Name</label>
<div class="col-sm-9">
<input type="text" ng-blur="performValidationQueryName()" ng-model="QueryName" ng-class="QueryNameError?'form-control validation_error':'form-control'" placeholder="Query Name" />
<span ng-if="QueryNameErrorMsg!=''" class="errorMsg">{{QueryNameErrorMsg}}</span>
</div>
<div class="clearfix"></div>
</div>
</div>
</div>
JavaScript code for blur event call is:
$scope.performValidationQueryName = function () {
if($scope.QueryName != null && $scope.QueryName != '') {}
};
The issue I'm facing is:
When ng-if="CurrentStage==='SaveQuery'" is there inside div, my ng-model="QueryName" is not getting updated. And with blur of the text, I get $scope.QueryName = "" with performValidationQueryName function.
If, I remove ng-if="CurrentStage==='SaveQuery'", all things works perfectly and I get the value inside the $scope.QueryName.
How can I call ng-blur which is placed inside the div with an ng-if condition?

You should use object in your input model will solve your problem because it comes under ng-if as shown below,
Template:
<div ng-if="CurrentStage==='SaveQuery'">
<div class="col-sm-12">
<div class="form-group row">
<label class="col-sm-3 control-label text-right">Query Name</label>
<div class="col-sm-9">
<input type="text" ng-blur="performValidationQueryName(Query.Name)" ng-model="Query.Name" ng-class="QueryNameError?'form-control validation_error':'form-control'" placeholder="Query Name" />
<span ng-if="QueryNameErrorMsg!=''" class="errorMsg">{{QueryNameErrorMsg}}</span>
</div>
<div class="clearfix"></div>
</div>
</div>
</div>
Controller:
$scope.performValidationQueryName = function (queryName) {
if (queryName != null && queryName != ''){
//do something..
}
};
