title: Angular material2 Autocomplete binding with complex object list doesn't behave as it should
body: <p>Autocomplete binding with a complex object doesn't behave as it should. I want to bind the autocomplete to complex object list and assign the selected complex object to another one but when I am doing it it is displaying [object object] in the autocomplete. I have also created the plunker to illustrate the issue</p>
  
  <p>Currently It works only with array list of string. Instead of the binding list with plain string list bind it with the list of complex object.</p>
  
  <p>I am using Angular Material v2.0.0-beta.3
