Opening a Quick Create form using JavaScript

Hello and thank you in advance....

I have some buttons in the ribbon and I want the quick Create Form to open when a user click on the button. 

I have already created the quick create form, so the form isn't created when you click the button.

I tried this two codes but it's not opening the form:

1. 

CustomQuickCreate.ShowQuickCreateForm("Account", "New Quick Create Form", function () { alert('Callback..!'); });

2. var destEntityToOpen = Xrm.Utility.openQuickCreate("Account","New Quick Create Form");
