Using simple JS within ionic sidemenu sample (AngularJS)

I am currently porting a Javascript "app" into AngularJS and one part of this app would be too long to recode.

What I would like to do is to use a simple javascript instruction like alert("message") within the ionic sideMenu sample available here : http://ionicframework.com/getting-started/

I already tried by including this into indext.html as well as in search.html but nothing would help

<script src="js/test.js" type="text/javascript"></script>

This is my test.js (I get no output for the console.log neither)

function test()
{
   console.log('test');
   alert("Secon test");
}
test(); //first method for calling the function, won't work

And calling it within an attribute won't work neither :

<ion-content class="has-header"  scroll="false" onload="test()">

Could you please tell me why this is not working and how to fix it? Thank you in advance
