Angular controller value seeming to revert to original value - angularjs

Question

After originally setting my controller weddingPrice value a change caused by a function does not seem to change the variable. Its probably a simple error- can anyone help?
When sendWeddingQuoteInfo() is called it seems to send the original weddingPrice, not the one which has been updated when the return journey toggle has been checked.
What should happen is that the wedding price should be set at the start through the local setup function. Then if the return journey toggle is switched to on, the returnJourneyChange() should be fired, changing the global weddingPrice. When the Submit Quote button is pressed this should take the updated weddingPrice and send it to the next page. Currently this does not happen- no idea why.

I think your ng-controller attribute is not at the right place. So the scope of your submit button is different.
I've moved the controller to ion-view element then the click is working as expected.
Please have a look at the demo below or here at jsfiddle.
(I've commented a lot of your code just to make the demo work.)
var app = angular.module('demoApp', ['ionic']);
app.controller('WeddingPaxCtrl', function($scope, $stateParams) { //, WeddingData, DataThrow) {
//var item = WeddingData.getWeddingDataObject();
$scope.passengerNo = 49;
$scope.returnJourney = {
checked: false
};
$scope.midnightReturn = {
checked: false
};
var weddingPrice;
$scope.returnJourney;
$scope.midnightReturn;
setup();
var sendInfo;
function setup() {
console.log("setup called");
weddingPrice = 100; //CostOfMarriage.getPrice(item[0], $scope.passengerNo, $scope.returnJourney.checked, $scope.midnightReturn.checked);
}
$scope.returnJourneyChange = function() {
console.log("return j called");
weddingPrice = 1000;
console.log("wedding price is now" + weddingPrice);
}
$scope.midnightReturn = function() {
}
$scope.getCostBreakDown = function() {
}
$scope.sendWeddingQuoteInfo = function() {
// var weddingPrice = $scope.weddingPrice;
console.log("WeddingPrice is " + weddingPrice + weddingPrice);
//var sendInfo = ["Wedding Hire", item[0], $scope.passengerNo, "Extra", weddingPrice];
//StoreQuoteData.setQuoteData(sendInfo);
//WhichQuote.setInfoLabel("Wedding");
}
