Fire a Stimulus Controller Action on a Click Event
In our Stimulus App, we change the connect method to a greet action (this method name can be anything.
We then wire that action up to our HTML button by adding data-action to it and passing the function that we want to fire, in this case, its click->example#greet.

Instructor: Here, we have a stimulus controller named example_controller. In our html, we're wiring up our controller to this div. Instead of firing console.log('Hello') on connect, we're going to change this to an action called greet.
The next thing we need to do is jump over to our html. We need to add a button. We'll give it a text of Greet. To wire up our greet action from our controller, we will add data-action="click." This is the DOM event that we're using.
We tell stimulus to fire our greet method in our example_controller. When we refresh, and we open up our developer tools, hop over to the console. When we click Greet, we'll get Hello.
To wrap up, all we did was create a method called greet on our controller class. We added a button to our html with an attribute of data-action and a value of click, which is the DOM event we want to fire our action on. Our action is our example_controller's greet method.
