title: how to get the search box value in angular datatable?
body: <p>I'm using <a href="http://l-lin.github.io/angular-datatables/#/welcome" rel="nofollow">angular datatable plugin</a>, and I want to get the value of the search box that comes with the generated datatable. Angular datatable has a few <a href="http://l-lin.github.io/angular-datatables/#/api" rel="nofollow">options</a> to make a datatable, but any of them allow me specify attributes or something that I could watch with the purpose to get a particular value.</p>
  
  <p>Since I need to get the value of the input search of the datatable, I can't find a way to accomplish my purpose. </p>
  
  <p><strong>So, how can I get the search box value in angular datatable?</strong></p>
