title: Force the input field for to have the first letter uppercase and the rest lowercase
body: <p>On SO there are many solutions to have the first letter uppercase and the rest lowercase. 
  But I want it to be forced instantly in the input field.</p>
  
  <p>I'm new to AngularJs and where I am working, we are using Angular 1.7.x.</p>
  
  <p>I have found something like this, but it doesn't work properly.</p>
  
  <pre><code>oninput="this.value = this.value.toUpperCase(0) + this.value.substring(1)"
  </code></pre>
