Issue
I am developing my first app using Angular and I can't see what's wrong.
I have used ui-bootstrap date with no issues in other places but then I tried using it inside a modal and whenever you pick a date inside the modal for the first time it works properly but then if you pick the wrong date and want to pick the correct one clicking the button to open the calendar a second time it doesn't work if it's inside the modal.
I have created a plunker sample where the error is reproduced.
Code fragments follows:
index.html
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<link data-require="bootstrap-css@3.1.1" data-semver="3.1.1" rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" />

})();
Solution
Scopes inherit from their parent scopes.
The modal is created as a child of the scope that you passed in when initalising it (or on the $rootScope by default). When attempting to set a property directly on the scope, angular will automatically create it for you. However, if you try doing model.myProperty, if model doesn't exist on the child scope, it will travel up to the parent and correctly set it there (if it exists).
A good description on how scopes work can be found here: https://github.com/angular/angular.js/wiki/Understanding-Scopes
Here is a working sample without having to resort to using $parent.

<input type="text" class="form-control" datepicker-popup="{{format}}" disabled
ng-model="dateModal.date" is-open="dateModal.opened"
ng-required="true" close-text="Close"/>
