I Want to add a Javascript code in website template, but in ONE specific template...

Example:

I have this template that is rendered by the controller in my website:

"""

<template id="solici" name="Form">
    <t t-call="website.layout">
         <div class="container">
            <iframe width="1100"
                    id="pm_iframe"
                    class="embed-responsive-item"
                    frameborder="0"
                    t-attf-src="{{pm_iframe}}"/>
        </div>
    </t>
</template>

"""

I want to manipulate the dom with this iframe to do something like this:

"""

var iframe = document.getElementById("myIframe");



// Adjusting the iframe height onload event

iframe.onload = function(){

    iframe.style.height = iframe.contentWindow.document.body.scrollHeight + 'px';

"""
