    show : function(component, event, helper) {
        var con=component.get("v.con");
        var action=component.get("c.create");
        action.setparams({"con":con});
        action.setCallback(this,function(response){
            var state =response.getState();
            if(state==="SUCCESS"){
               var result=response.getReturnValue();
                console.log('Result:'+result);
                component.set("v.result",result);
            }else{
                console.log('Failed');
            }
            
        });
        $A.enqueueAction(action);
          }
})
when after insertion when i am cicking submit button i am getting Error
This page has an error. You might just need to refresh it. Action failed: c:Sobject_ex$controller$show [action.setparams is not a function] Failing descriptor: {c:Sobject_ex$controller$show}
