+ * @description
+ * autocompleteTrigger allows you to specify a trigger (e. g. @ like twitter or facebook) and bind it to a textarea or input text field.
+ * If a user writes the trigger-sign into the textbox, the autocomplete dialog will displayed and the text after the trigger-sign
+ * will be used as search-query for the autocomplete options. If one of the suggested items will be selected, the value and trigger
+ * will be added to the textfield.
