I have a class where I have declared @RemoteAction functions to work using Javascript Remoting.

When I only had one function everything was working fine, but when I created a second @RemoteAction function the browser console was displaying the following error:

Visualforce Remoting Exception: Method 'getCallsDetail' not found on controller RqaCallsList. Check spelling, method exists, and/or method is RemoteAction annotated.

I checked the javascript code and also the Apex code and everything is ok, there are not problems with the names or anything like that.

Javascript code:

RqaCallsList.getCallsList(startDate, endDate, token, function(result,event){
        if(event.status){
            results = result;
            var headers = ['Date','Campaign','Campaign Type','Disposition','Agent','Call Recording','QA Score','ANI','DNIS'];
            var tableContent = createTable(results,headers);
            table.empty();
            table.append(tableContent);
            toDataTable(table);
            $j('#loading').hide();
        }
    });
}


RqaCallsList.getCallsDetail(startDate, endDate, token, function(result,event){
        if(event.status){
            results = result;
            var headers = ['Date','Campaign','Campaign Type','Disposition','Agent','Call Recording','QA Score','ANI','DNIS'];
            var tableContent = createTable(results,headers);
            table.empty();
            table.append(tableContent);
            toDataTable(table);
            $j('#loading').hide();
        }
    });
}

Apex code:

@RemoteAction
    public static List<Call__C> getCallsList(String startDate, String endDate, String token){
        calls = new List<Call__c>();
        identifier = sendCallLogRequest(startDate, endDate, token);
        isRunning = checkCallLogIsRunning(identifier, token);
        if(isRunning)
            calls = getCallLogResult(identifier, token);
        else{
            MessageManager.addMessage(ApexPages.Severity.ERROR, 'The call log service is not running');
            return null;
        }
        return calls;
    }

@RemoteAction
    public static List<Call__C> getCallsDetail(String startDate, String endDate, String token){
        calls = new List<Call__c>();
        identifier = sendCallLogRequest(startDate, endDate, token);
        isRunning = checkCallLogIsRunning(identifier, token);
        if(isRunning)
            calls = getCallLogResult(identifier, token);
        else{
            MessageManager.addMessage(ApexPages.Severity.ERROR, 'The call log service is not running');
            return null;
        }
        return calls;
    }

The syntax is correct because I'm using a Static Resource where I have all the javascript functions.

What could be wrong with my code?

Thanks in advance
