ember removeObserver and addObserver - ember.js

Question

I have an array property named 'checked' that I'm observing and I want to temporarily disable observation while I update the property. What is the correct syntax for removeObserver and addObserver?
applyPreReqs: function() {
var currentContent = this.get('content');
currentContent.entitlements.forEach(function(entitlement) {
if (entitlement.checked && entitlement.prerequisiteEntitlementIds !== undefined) {
entitlement.prerequisiteEntitlementIds.forEach(function(prereq) {
currentContent.entitlements.forEach(function(item) {
if (item.id === prereq && !item.checked) {
Ember.set(item, 'checked', true);
}
});
});
} else {
currentContent.entitlements.forEach(function(item) {
if (item.id !== entitlement.id && item.checked) {
Ember.removeObserver('content.entitlements.#each.checked', this, this.applyPreReqs);
Ember.set(item, 'checked', false);
Ember.addObserver('content.entitlements.#each.checked', this, this.applyPreReqs);
}
});
}
}.observes('content.entitlements.#each.checked')
Thank you!

I don't all that you are doing here but this is how you remove the array observer and then make your updates then add the observe back as the observe is fired.
applyPreReqs: function() {
var currentContent = this.get('content');
currentContent.entitlements.forEach(function(entitlement) {
....
}
currentContent.entitlements.removeArrayObserver(this);
}.observesBefore('content.entitlements.#each.checked')
applyPreReqs: function() {
var currentContent = this.get('content');
currentContent.entitlements.forEach(function(entitlement) {
....
}
currentContent.entitlements.addArrayObserver(this);
}.observes('content.entitlements.#each.checked')
I hope this helps
Cheers
