title: How can I programatically clear the search fields in smart-table?
body: <p>I'm using smart-table at the moment, and I have input text boxes up the top of each column and I am using st-search.  The point of what I am making is something is selected from the table, and then the results in the table are changed.</p>
  
  <p>I am trying to clear the search boxes when the row is clicked.  At the moment other business logic is implemented on click, so it's at this point that I am looking to clear these text boxes.</p>
  
  <p>I have tried to associate an ng-model to these text boxes, and to clear them when the row is clicked but the text boxes don't change.  I have also googled this issue and I have only found solutions on how to make this work for when you click on a button (by a directive) to clear the predicates.  I haven't been able to make these solutions work programatically however.</p>
