title: AngularJS ng-grid with custom button
body: <p>I am using angular button in a <a href="http://angular-ui.github.com/ng-grid/" rel="noreferrer">ng-grid</a>. I need to know how can i identity which button was clicked from within the grid.</p>
  
  <p>I guess part of the complexity is that the button is clicked before the row is selected (Just my analysis,probably wont help with the solution :)</p>
  
  <p>A snap shot of how the grid looks</p>
