title: React Native unit for text input value
body: <p>I want to add unit to a <code>textInput</code> value:</p>
  
  <p><a href="https://i.stack.imgur.com/EqswS.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/EqswS.jpg" alt="enter image description here"></a></p>
  
  <p>I've tried to use <code>value = { this.state.totalWeight + " Kgs"}</code> but no result!</p>
  
  <p>Also I tried to add the <code>" Kgs"</code> in <code>onSubmitEditing = { () =&gt; { this.refs.firstInput.refs.value = this.state.totalWeight + " Kgs" }</code> but again, no result!</p>
  
  <p>Any idea?</p>
