My rendered partial '_form' appears, but is not submitting

Ruby 2.1.5 on Rails 4.2.0:

I have two directories. One directory is a rails-generate scaffold named 'inqueries'. The other directory is named 'welcome', which only houses a landing paged named index.html.erb. The inquery form works & submits fine as long as I'm using the view from the actual 'inquery' scaffold/directory.

I am able to render the inquery _form on my index.html.erb landing page using :

 <%= render partial: "inqueries/form", locals: {inquery: @Inquery} %>

However, this JUST renders the form. When I hit the submit button, no errors, flash messages, or inquery is submitted. It is complete non-action, including on my rails terminal.

How can I properly make the form work on my landing page?

Here is my welcome_controller.rb file. This controller handles the landing page where I am trying to render the inquery scaffold's form:

class WelcomeController < ApplicationController

      def index
        @inquery = Inquery.new
        render layout: false
      end
    end

This is my new rails scaffold-generated method in the inqueries_controller.rb:

  def new
    @inquery = Inquery.new
    respond_with(@inquery)
  end

Sorry, Here is the Inquery _form itself:

<%= form_for(@inquery) do |f| %>
    <div id="error_explanation">
        <% if @inquery.errors.any? %>
            <h2>
                <%= pluralize(@inquery.errors.count, "error") %> prohibited this inquery from being saved:
            </h2>
            <ul>
                <% @inquery.errors.full_messages.each do |message| %>
                <li><%= message %></li>
            </ul>
        <% end %>
    </div>
<% end %>
<br />
<form role="form">
    <div class="col-lg-12">
        <div class="form-group col-lg-4">
            <%= f.label t('.name') %><br>
            <%= f.text_field :name, class: "form-control" %>
        </div>

        <div class="form-group col-lg-4">
          <%= f.label t('.email') %><br>
          <%= f.text_field :email, class: "form-control" %>
        </div>

        <div class="form-group col-lg-4">
          <%= f.label t('.phone') %><br>
          <%= f.text_field :phone, class: "form-control" %>
        </div>

        <div class="clearfix"></div>
        <div class="form-group col-lg-12">
            <%= f.label t('.message') %><br>
            <%= f.text_area :message, rows: 8, class: "form-control"%>
        </div>
        <div class="form-group col-lg-12">
            <input type="hidden" name="save" value="contact">
            <%= f.submit t('.submit'), class: "btn btn-primary" %>
        </div>
    </div>
</form>
<% end %>
