Python requests_html submit a form by clicking a button using JQuery

Question

I'm exploring Kenneth Reitz's requests_html and trying to submit a form of a JS Rendered Webpage using Jquery. I'm not sure how to do it but, here is my attempt:

from requests_html import HTMLSession
url = "https://example.com"
session = HTMLSession()
r = session.get(url)
r.html.render()
script = """
       () => {
         $("#some_input_field").val("Some value");
         $("#submit_button").click();
         }
         """
r.html.render(script=script, reload=False)

But, the value is not getting set on the input field & it isn't submitting the form... Is there any way to simulate button click or, form submit via xhr in requests_html?

For example: If we use selenium we can simulate button click pretty easily by typing:

element.click()

Ok, The following code is working in my case:

from requests_html import HTMLSession
url = "https://example.com"
session = HTMLSession()
r = session.get(url)
r.html.render()
script = """
       () => {
              if ( jQuery.isReady ) {  
                   $("#some_input_field").val("Some value");
                   $("#submit_button").click();
              }
        }
         """
r.html.render(script=script, reload=False)

EDIT: A better approach should be:

from requests_html import HTMLSession
url = "https://example.com"
session = HTMLSession()
r = session.get(url)
r.html.render()
script = """
       () => {
              $(document).ready(function() {  
                   $("#some_input_field").val("Some value");
                   $("#submit_button").click();
              })
        }
         """
r.html.render(script=script, reload=False)
