Rishi Anand told you everything you needed but, to give a simple example of another way of doing it, see here.

Can you share the code where you tried this? it's kinda hard to say because it all depends on what you want to do when the button is clicked, anyone can suggest a sample code but no one knew what you want to do. So share the code please, or at least elaborate more on what you want to do with the button.
Here's how you share links, in case you didn't know yet:

In case of a simple alert you can simply add this in your document's body.
<button type="button" onclick="alert('Hello world!')">Hello world</button>

Use can use add event listener
<button id="btn">click</button>
Now add the following code in JavaScript
document.getElementById("btn").addEventListener("click", function() {alert("hello world!!");});

The three ways of adding event listeners (and also why the third way is better) :
