execute a function that invokes a class method

Within my component, I have implemented a method that includes a jQuery event binding functionality.

jqueryNextDataEditableShow() {
    $('#symbolTable .editable').on('hidden', function (e, reason) {
      if (reason === 'save' || reason === 'nochange') {
        var $next = $(this).closest('td').next().find('.editable');
        if($next != undefined && $next.length == 0){
          //perform certain actions here
        }
        setTimeout(function () {
          $next.editable('show');
        }, 300);
      }
    });
  }

In addition to this, there exists another method named onSimulate() within the class.

onSimulate(){
   console.log("onSimulate Method Called");
}

I aim to invoke the onSimulate() method at the designated location marked by a comment inside the jqueryNextDataEditableShow(). However, I am encountering an issue where the this keyword within the function refers to the document tag or element instead of the intended scope.

Consider using arrow functions => like this -

jqueryNextDataEditableShow() {
    $('#symbolTable .editable').on('hidden',  (e, reason) => {
      if (reason === 'save' || reason === 'nochange') {
        var $next = $(this).closest('td').next().find('.editable');
        if($next != undefined && $next.length == 0){
          //call the respective method
        }
        setTimeout(() => {
          $next.editable('show');
        }, 300);
      }
    });
  }
