How to set up a Count from my Controller in Rails - html

Question

I'm new to ruby on rails so please forgive the question. I tried following this example How to "count" user inputs from a Controller but kept getting nothing in my view. I am trying to create a count functionality on my share feature (similar to retweet which works perfectly now). >> So whenever a user shares a tweet there is a counter that changes with it as well. I have listed below all my relevant code. Thank you so much guys!!
tweets_controller.rb
class TweetsController < ApplicationController
before_action :set_tweet, only: [:show, :edit, :update, :destroy, :share]
def index
#tweets = Tweet.all
end
def share
tweet = current_user.tweets.create(tweet_id: #tweet.id)
if tweet.save
redirect_to tweets_path
else
redirect_to :back, alert: "Unable to share"
end
end
_share.html.erb
<div>
<div>Shared by <%= tweet.user.username %></div>
<%= render partial: "tweets/tweet", locals: {tweet: tweet.tweet} %>
</div>
_tweet.html.erb
<div class="row">
<div class="col-md-3"><%= tweet.watches_count %><%= render partial: "watches", locals: {tweet: tweet} %></div>
<div class="col-md-3"><%= link_to '<i class="fa fa-share fa-lg" aria-hidden="true"></i>'.html_safe, share_tweet_path(tweet), method: :post %></div>
<div class="col-md-6"><span class="pull-right"><%= tweet.likes_count %><%= render partial: "likes", locals: {tweet: tweet} %></span></div>
</div>
</div>
routes.rb
Rails.application.routes.draw do
resources :tweets do
resource :like, module: :tweets
resource :watch, module: :tweets
member do
post :share
end
end
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }
resources :users, :controllers => "users_controller.rb"
root to: "tweets#index"
end
Migration CreateTweets
class CreateTweets < ActiveRecord::Migration[5.0]
def change
create_table :tweets do |t|
t.text :body
t.integer :user_id
t.integer :tweet_id
t.timestamps
end
end
end
Relevant Rake Routes
share_tweet POST /tweets/:id/share(.:format) tweets#share
tweets GET /tweets(.:format) tweets#index
POST /tweets(.:format) tweets#create
