field value +1

Hello! I trying to add +1 to field with the code below. But did not succeed
        var a = {!Activity__c.SF1_Attempts__c};
        function plus(){
        document.getElementById('page:form:Attempts').value = a + 1;


Attempts : <apex:inputField id="Attempts" value="{!Activity__c.SF1_Attempts__c}" />
