Chef12 - application_name params set in wrapper cookbook

I am using chef 12 version trying to overwriting an apache2 template using a wrapper cookbook. My chef-client does not fail but it doesn’t add the application_name = testcom. How do I add that application_name in the param in my template wrapper? If I remove @application_name and change it to @params[:name] it does what I want it to do, is there a better way to do it without modifying the wrapper template?

My wrapper template:

 <%- if node['apache']['version'] == '2.4' -%>
LogLevel info rewrite:trace1
<%- else -%>
LogLevel info
RewriteLog <%= node['apache']['log_dir'] %>/<%= @application_name %>-rewrite.log
#   RewriteLog <%= node['apache']['log_dir'] %>/<%= @params[:name] %>-rewrite.log
RewriteLogLevel 0
<% end -%>

This is the apache2, Definition web_app community cookbook

define :web_app, :template => 'web_app.conf.erb', :local => false, :enable => true, :server_port => 80 do
 application_name = params[:name]

include_recipe 'apache2::default'
include_recipe 'apache2::mod_rewrite'
include_recipe 'apache2::mod_deflate'
include_recipe 'apache2::mod_headers'

template "#{node['apache']['dir']}/sites-available/#{application_name}.conf" do
source params[:template]
local params[:local]
owner 'root'
group node['apache']['root_group']
mode '0644'
cookbook params[:cookbook] if params[:cookbook]
variables(
  :application_name => application_name,
  :params           => params
)
if ::File.exist?("#{node['apache']['dir']}/sites-enabled/#{application_name}.conf")
  notifies :reload, 'service[apache2]', :delayed
 end
end

site_enabled = params[:enable]
apache_site params[:name] do
enable site_enabled
end

The output from the chef-client run doesn’t give an error but removes the testcom (-rewrite.log) in line 4
