How do I call a function inside of another function from java script file in html file?

Question

I want to call the function that is in another function in my HTML file here is my HTML code:

    <input type="radio" name="layerButton" value="UnTiled" id="raster" onclick="if(this.checked){myFunction()}">Raster Layer
    <script type="text/javascript" src="./main.js" ></script>

and here is my javascript code(main.js):

function init(){
function myFunction() {
    alert('hi')
}
}

and error is :

Uncaught ReferenceError: myFunction is not defined

I think Beller's comment is the answer. I hope he/she will post it as an answer as well. — Miu

return myFunction();

To add some context to the other answer, you are not able to run conditional statements using onClick, only functions.
