title: AEM/CQ5 Dialog multifield not saving input
body: <p>I am building a component which allows the user to add a multi field. When the multifield is added to the dialog, the user is presented with two text boxes. When the user adds information to the text boxes, and clicks 'OK'. When the dialog closes, no information is stored/saved.</p>
  
  <p>Can anyone point out where I've gone wrong?</p>
  
  <p>See the dialog code below:</p>
