title: Set value of numberfield without firing "change" event in Sencha Touch
body: <p>I have a numberfield and a list in Sencha Touch.  When I click on an item in the list, I am doing an AJAX request to send data to the server.  However, if there is data in the numberfield, I want to clear that when the list is clicked on.  <p>I have no problem doing this (I am setting the value to a blank string), however, the change event is fired on the numberfield.  This causes another AJAX request to run which doesn't need to.  Is there any way to clear a numberfield WITHOUT firing the change event?  SuspendEvents does not work as clearing the numberfield requires an event.  <p>Any thoughts or suggestions?  Thanks!<p><p><p>Code lines that I have tried:<p> <code>suspendEvents();</code> <code>me.getWhatScreen().down('numberfield[name=caseNumber]').setValue('');</code> <code>resumeEvents(true);</code> <p> <code>me.suspendEvents();</code> <code>me.getWhatScreen().down('numberfield[name=caseNumber]').setValue('');</code> <code>me.resumeEvents(true);</code></p>
