title: Input Field With Custom Input Method
body: <p>I would like to show a custom input field (specifically, one containing only 9-0 and two extra buttons containing decimal separator (, or .) and a delete button).</p>
  
  <p>I could create a custom IME, but (as far as I know) that would have to be set by the user as the system-wide input method. Is there a way to implement an input method and bind it to a specific input field?</p>
  
  <p>Thanks for the help!</p>
