arcgis server - Toggle Identify with Button

I am attempting to set up an Identify button that will only allow the identify functionality to be performed when the button is pressed. I have gotten to the point that the identify only works when the button has been pushed the first time but I can't seem to turn the button off. I have pasted a few bits of code below or you can follow the link to see the entire thing.

Funtion to activate Identify

function activateIdentify(){
    if (dijit.byId("tool_identify").checked) {
        dojo.connect(map, "onClick", executeIdentifyTask);
    }
  }

Button to Activate function

Identify

Function to toggle buttons

function toggleButtonIcon(tool) {

    //only the tools in the toolbar are dijit togglebuttons so can iterate thru them
    dijit.registry.byClass("dijit.form.ToggleButton").forEach(function(togbtn) {
      if (togbtn == tool) {
        togbtn.attr("checked", true);

      }
      else {
        togbtn.attr("checked", false);
      }
    });
  }  //end toggleButtonIcon

Thanks for your help.

Mike,

Set a global variable to hold the "onClick" listener, then disable the listener when the button is disabled.

var identifyListener;

function activateIdentify(){
  if (dijit.byId("tool_identify").checked) {
    identifyListener = dojo.connect(map, "onClick", executeIdentifyTask);
  } else {
    dojo.disconnect(identifyListener);
  }

}
