Button no longer Triggering Workflow

Button no longer Triggering Workflow

I have a button I created to check a box.  The button function is simple: 
  2. zoho.crm.updateRecord("Deals",id.toLong(),{"Send_Email_IA":true},{"trigger":"workflow"});
  3. zoho.crm.updateRecord("Deals",id.toLong(),{"Send_Email_IA":false},{"trigger":"workflow"});
  4. updateRec = zoho.crm.updateRecord("Deals",id.toLong(),{"trigger":{"workflow"}});
  5. return "Sent";

I then have a workflow shown below:



This "used" to send an email when the button was pressed.  However, the button is no longer triggering the workflow.  What am I missing?  In my timeline I can see that the button is in fact changing the field from "false" to "true" and back.  Also, if I go manually uncheck the box it triggers the workflow.  I'm at a loss...please help.
