Second paragraph

The initialize function uses a jQuery selector that doesn't match the markup. ... initialize: function() { this.allCheckbox = this.$('#toggle-all')[0]; } ... Should be: ... initialize: function() { this.allCheckbox = this.$('#toggle-all'); } ... Because we're selecting the element by id, only one element will be returned. The printed code results in this.allCheckbox being undefined.

Note from the Author or Editor:
Please make the suggested change as recommended by the feedback. This is a confirmed issue.
