Custom JS code

Hi,
I have added a custom JS script to my AMP page.
Code added in this section of the plugin : Enter HTML in Body (beginning of body tag)
Code added is : <amp-script layout=”container” src=”path_to_file”></amp-script>

The code is added to my AMP pages but is not executed. This code is working fine on non-AMP page.

Do you have any ideas about this issue ?
Thanks
