How to call Function in Javascript Magento2

I want to show alert using function in phtml file as per below but it seems like the function (myfunction) is not calling.

<button onclick="myFunction()">Try it</button>

<script type="text/javascript">
require(['jquery'], function($){
    function myFunction() {
      alert("I am an alert box!");
    }
})
</script>
