Modal Factory to be used in place of Confirm() - angularjs

Question

I have created an Angular Modal factory that passes a couple parameters to create dynamic modals based upon templates and options passed back. However I want to replace all of the Confirm dialogues in my app but am struggling with this.
modal factory
(function () {
var testApp= angular.module('test');
testApp.factory('myModals', ['$uibModal', function ($uibModal) {
// called from various methods within factory
function openModal(template, data, options) {
//build all of the modal options
var modalOpts = {
animation: true,
templateUrl: template,
controller: function ($scope, $uibModalInstance, alert_data) {
$scope.alert_data = alert_data;
$scope.okToProceed = function () {
$scope.goodToGo = true;
console.log("true")
};
$scope.cancel = function () {
$uibModalInstance.dismiss('cancel');
console.log("modal cancelled")
};
},
resolve: {
alert_data: data
},
size: '480',
backdrop: 'static'
};
// extend options set in each use type function
if (options) {
angular.extend(modalOpts, modalOpts);
}
var modalInstance = $uibModal.open(modalOpts);
modalInstance.result.then(function (data) {
// always do something when close called
return data;
}, function (data) {
//always do something when dismiss called
return data
});
return modalInstance;
}
function alert(type, text, size) {
var template;
// enter in template and string being passed back to identify modal type
switch (type) {
case 'test1':
template = 'test1.popup.html';
break;
case 'test2':
template = 'test2.popup.html';
break;
}
var opts = {
//default but should be passed back
size: size || 'sm'
};
var data = {
title: type === 'success' ? "OK" : "Error",
text: text
};
return openModal(template, data, opts);
}
return {
alert: alert
}
}])
})();
template.html
<div class="modal-header">
<h3 class="modal-title"></h3>
</div>
<div class="modal-body">
<h3>{{alert_data.text}}</h3>
</div>
<div class="modal-footer">
<button class="btn btn-warning" type="button" ng-click="okToProceed()">Ok</button>
<button class="btn btn-warning" type="button" ng-click="cancel()">Cancel</button>
</div>
example of confirm to be replaced
$scope.discardSource = function(currentIndex) {
if (confirm("Press 'OK' to confirm.")) {
$log.debug("discardDataSource currentIndex: " + currentIndex);
$log.debug($scope.model.dataSamples[currentIndex]);
