We've upgraded from v7.2.2 to 7.6.1, and we're getting an error in the Umbraco backoffice, where a date picker exists in a custom dashboard.

We've implmented a datetimepicker, which you can see here.

The error we're seeing is: $element.find(...).datetimepicker is not a function.

Google search seems to suggest that JQuery should be loaded first, which in the install.loader.js, it is..

LazyLoad.js( [
  'lib/jquery/jquery.min.js',
  /* 1.1.5 */
  'lib/angular/1.1.5/angular.min.js',
  'lib/angular/1.1.5/angular-cookies.min.js',
  'lib/angular/1.1.5/angular-mobile.min.js',
  'lib/angular/1.1.5/angular-mocks.js',
  'lib/angular/1.1.5/angular-sanitize.min.js',
  'lib/underscore/underscore-min.js',
  'js/umbraco.installer.js',
  'js/umbraco.directives.js'
], function () {
    jQuery(document).ready(function () {
        angular.bootstrap(document, ['ngSanitize', 'umbraco.install', 'umbraco.directives.validation']);
    });
}
);

Any thoughts..?
