title: ag-grid React refreshCells is not affected by state changes
body: <p>my react grid has a some row values that depends on state (Actually has a slider column).</p>
  
  <p>But i need to show new slider value after state changed by slider. I did it by call <code>redrawRows()</code> because <code>refreshCells()</code> is not changing cell value as state. <code>refreshcells</code> is does nothing into slider.</p>
  
  <p><code>redrawRows</code> working good but losing mousedown event on slider. i changing slider value with mouse and slider's mousedown handling is lost after <code>redrawRows</code>. I must re press mouse button on every slider value change</p>
  
  <p>Why <code>refreshCells</code> does not update cell value?</p>
