The method you called is not defined

Error message

The method you called is not defined

What it means

Emitted by Checkbox's invoke() dispatcher (checkbox.js:730) when a string method name does not resolve to any property on the checkbox module instance — a typo or a method absent in this version. Unlike the dead-config modules, Checkbox actually logs this via module.error (checkbox.js:643), which is a bound console.error controlled by settings.silent. It is not a thrown exception.

Solutions

1. Use a documented method: 'toggle', 'check', 'uncheck', 'indeterminate', 'determinate', 'enable', 'disable', 'refresh', etc.
2. Verify the method exists in your installed Semantic UI version.
3. Set silent:true only to hide the console noise after confirming it is benign.

Example fix

// before
$('.checkbox').checkbox('togglee'); // typo -> console.error
// after
$('.checkbox').checkbox('toggle');

// Validate the method against the checkbox module before invoking.
var checkboxMethods = ['toggle','check','uncheck','indeterminate','determinate','enable','disable','set enabled','set checked','set unchecked','set indeterminate','set determinate','is radio','is checked','is unchecked','is indeterminate','is enabled','is disabled','refresh','destroy'];
function callCheckbox($el, method, args){
  if (checkboxMethods.indexOf(method) === -1) {
    throw new Error('Unknown checkbox method: ' + method);
  }
  return $el.checkbox(method, args);
}

When it happens

Trigger: $('.checkbox').checkbox('togglee') (typo) or any string that fails the camelCase/dotted lookup against the module instance (checkbox.js:714-732).

Common situations: Misspelled method name, wrong-version docs, calling a method that belongs to a different module.
