I have an issue related to AJAX - ruby

Question

I need to get the value after it is created, just below the section "NEW"
Below is the image I intended to do, and after the data was created I wanted it right there
phrases_term_controller.rb
class PhrasesTermsController < ApplicationController
before_action :authenticate_user!
before_action :set_term
def new
#phrases_term = PhrasesTerm.new
end
def create
#phrases_term = #term.phrases_terms.new(phrases_term_params)
if #phrases_term.save
redirect_to term_phrases_term_path(#term, #phrases_term), notice: "Phrases_Term was successfully created"
else
render "new"
end
end
def show
#phrases_term = PhrasesTerm.find(params[:id])
end
private
def phrases_term_params
params.require(:phrases_term).permit(:term_id, :phrase_id)
end
def set_term
#term = Term.find(params[:term_id])
end
end
View
phrases_term
new.html.erb
<h1><%= I18n.t("pages.phrases_term.new.title") %></h1>
<%= render 'form', phrases_term: #phrases_term %>
_form.html.erb
<%= form_with scope: :phrases_term, url: term_phrases_terms_path, local: true do |form| %>
<% if phrases_term.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(phrases_term.errors.count, "error") %> prohibited this phrase from being saved:</h2>
<ul>
<% phrases_term.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= form.label :term_id %> :
<%= form.number_field :id %>
</div>
<div class="dropdown">
<button class="dropbtn">Phrase</button>
<div class="dropdown-content">
<a><%= form.select :phrase_id, Phrase.all.collect { |p| [ p.id ] }, include_blank: true %></a>
</div>
</div>
<div class="actions">
<%= form.submit %>
</div>
<% end %>
Term:
_form.html.erb
<%= form_with(model: term, local: true) do |form| %>
<% if term.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(term.errors.count, "error") %> prohibited this term from being saved:</h2>
<ul>
<% term.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= form.label :word %>
<%= form.text_field :word %>
</div>
<div class="field">
<%= form.label :meaning %>
<%= form.text_field :meaning %>
</div>
<div class="field">
<%= form.label :reading %>
<%= form.text_field :reading %>
</div>
<div class="actions">
<%= form.submit %>
</div>
<% end %>
