How to call apex function from Visualforce in Salesforce1

Hi everybody,
I have the following situation, We have in our org a JS button in the layout that call a method in an apex class to send an Email. But in salesforce1 this doesnt works then what I did is create a VF with the same code as the button and calling this VF with a custom Action. Now in Salesforce1 I can see the action but the only thing that do this action is open a blank page with the name of the VF and the buttons cancel and save but doesn't execute the class.
The code in the VF page is: 
<apex:page standardController="Invoice__c">
	<apex:includeScript value="/soap/ajax/15.0/connection.js"/>
	<apex:includeScript value="/soap/ajax/15.0/apex.js"/>
	<script>
	
		var result = sforce.apex.execute('sendInvoice', 'send',{invoiceId:'{!Invoice__c.Id}'}); 
	
		if(result == ''){ 
			window.location.reload(); 
	
		}else{ 
			alert(result); 
		}
	</script>
</apex:page>
and the class is: 
global with sharing class sendInvoice {
	
	webservice static String send(ID invoiceId) {
		
		Invoice__c inv = [Select Id, Status__c From Invoice__c Where Id =:invoiceId];
		
		if(inv != null && inv.Status__c =='Approved'){
			try {
				//....More code here
				return '';
			} catch(Exception e) {
				System.debug('@@@@ Error: ' + e);
				return 'Unexpected error, please contact with your Administrator';
			}	
		}else{
			return 'Invoice status should be Approved';
		}
	}
    
}
In salesforce classic this works fine but in Salesforce1 I can't find a solution.
Anyone can help me with this??

Thanks

Try creating an extension class and put the logic in that class, in the constructor as needed.

<apex:page standardController="Invoice__c" extensions="LogicExecutionClass">

You may need to change your code since you are already in APEX, so no need to use AJAX

Thx

Thanks William now is working, I was focused in doing that with JS and I don't think in doing in that way.
