title: Adding checkbox to simple form for input not in model
body: <p>I'm trying to add a checkbox input to my simple form in Rails. I only need the input for javascript and don't actually want it in my model file.</p>
  
  <p>I've learned that in order to add inputs to simple form that do not exist in the model a value has to be passed in the parameters</p>
  
  <pre><code>input_html: {value: true}
  </code></pre>
  
  <p>This works for a text input, but I can't get it working for a checkbox.</p>
  
  <p>I've tried</p>
  
  <pre><code>&lt;%= f.input :current_job, :as =&gt; :check_box, input_html: {value: false} %&gt;
  </code></pre>
  
  <p>and</p>
  
  <pre><code>&lt;%= f.input :current_job, :as =&gt; :check_box, input_html: {checked: false} %&gt;
  </code></pre>
  
  <p>But I get an error saying</p>
  
  <pre><code>No input found for check_box
  </code></pre>
