title: Slickgrid breakpoint on filter
body: <p>Looking at the Slickgrid examples and using Google Chrome, I'm setting a breakpoint on the filter to see what's going on internally. The breakpoint works fine on line 87 <a href="http://mleibman.github.com/SlickGrid/examples/example-header-row.html" rel="nofollow">http://mleibman.github.com/SlickGrid/examples/example-header-row.html</a></p>
  
  <p>but it doesn't work on line 143</p>

  <p>Why not?</p>
