dojo1.8 - Need on.pausable(fire, 'change', function()) to trigger select toggleDropdown and focus methods - dojo

Question

Hi I have a problem and the error stated:- "Error: Target must be an event emitter."
If there is a change in fire variable and selectHandler is resumed, shouldn't the methods be triggered - toggleDropDown and focus?
Here's my code below:-
var fire = false;
var toggle1, toggle2 = true;
var select = new Select
({
store:storeA
}, 'node_Select');
select.startup();
fire = true;
var switchStore = new button
({
onClick: function()
{if (toggle1)
{
select.setStore(storeB);
toggle1 = false;
}
else
{
select.setStore(storeA);
toggle1 = true;
}
fire = true;
}
}, 'node_switchStore');
switchStore.startup();
var selectHandler = on.pausable(fire, 'change' function()
{
if(fire)
{
select.toggleDropDown();
select.focus();
fire=false;
}
})
var switchPause = new button
({
onClick: function()
{if (toggle2)
{
selectHandler.resume();
toggle2 = false;
}
else
{
selectHandler.pause();
toggle2 = true;
}
}
}, 'node_switchPause');
switchPause.startup();
What is event emitter? Only input change, button and DOM elements' events?
It seems that the fire variable is not event emitter, isn't it?
Please advise

It has to do with this line:
var selectHandler = on.pausable(fire, 'change' function()
You're trying to listen to one of javascripts primitive types, Boolean. In order for "dojo/on" to work, it has to listen to something that can fire off events. From what I'm seeing in your code sample, what you probably need is a function that handles the changing of the "fire" variable. How about something like this:
var openFire = function() {
select.toggleDropDown();
select.focus();
fire = false;
}
now instead of setting
fire=true;
you can just call
openFire();
