Ionic - text input in a modal crashes the app on ios - ionic-framework

Question

I have a text input field for my form that I am trying to fill out using a modal. But the app crashes on me. The problem occurs on the ios device. It doesn't occur on the web / ionic serve. I didn't test it on Android because I don't own a device. My other Modals work fine.
Repro Steps:
Tap on the modal item
Model Opens
Enter a value in the text field
4 Tap Save Button - The value is returned to the main controller
Tap again to edit the value - The app will hang
If Steps 1,2,3 are repeated by restarting the app and Done button on the device keyboard is tapped it also hangs.
Function Inside Main Controller:
// Code for my Modal Controller:
$ionicModal.fromTemplateUrl('templates/mymodal.html', function(modal) {
$scope.gmodalCtrl = modal;
}, {
scope: $scope,
animation: 'slide-in-left',
focusFirstInput: true
});
$scope.gmodalData = {"merchtype" : 'Please pick one'};
$scope.opengModal = function() {
$scope.gmodalCtrl.show();
};
MyApp.controller('MyController', function($scope) {
$scope.hideModal = function() {
$scope.gmodalCtrl.hide();
};
$scope.item = {};
$scope.doSomething = function(item) {
console.log('going with G Modal');
$scope.gmodalData.myrange = $scope.item.myrange;
console.log($scope.gmodalData.myrange);
console.log($scope.item.myrange);
$scope.gmodalCtrl.hide();
};
});
// HTML to Invoke Modal:
<label class="item"> <button class="button icon-right ion-ios7-arrow-right button-clear button-dark" ng-click="opengModal()">Merchant Name: {{gmodalData.myrange}} </button> </label>
// Modal HTML:
<input type="text" style="width: 250px" ng-model="item.myrange">
<button class="button button-block button-balanced" ng-click="doSomething()">Do it</button>
Output in the Xcode Debugger:
Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(
"<NSLayoutConstraint:0x176b75b0 V:|-(20)-[UIInputSetContainerView:0x176b5f70] (Names: '|':UITextEffectsWindow:0x176b3960 )>",
"<NSLayoutConstraint:0x176a3210 'UIInputWindowController-top' V:|-(0)-[UIInputSetContainerView:0x176b5f70] (Names: '|':UITextEffectsWindow:0x176b3960 )>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x176b75b0 V:|-(20)-[UIInputSetContainerView:0x176b5f70] (Names: '|':UITextEffectsWindow:0x176b3960 )>
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

I get the same problem, my xCode is 7.2(7C68), ionic 1.7.12, cordova 5.1.1, iOS 9.2.
I fix this problem by adding another plugin.
Please checkout.
https://github.com/driftyco/ionic-plugin-keyboard
ionic plugin add ionic-plugin-keyboard
ionic build ios
then install this app with xCode, the button works.
Hope it will help you.
