Controller Code

({
	loadOptions: function(component, event, helper) {
	var action=component.get("c.accountType");
    action.setCallback(this, function(response){
     component.set("v.Type",response.getReturnValue())
        });
        $A.enqueueAction(action);
	},
    clickCreate : function(component, event, helper) {
		var newAccount=component.get("v.newAccount");
        console.log(newAccount);
        if($A.util.isEmpty(newAccount.Name) || $A.util.isUndefined(newAccount.Name)){
            alert(' Name is Required');
            return;
        }
        
        
        console.log("Create Account: " + JSON.stringify(newAccount));
        var b=JSON.stringify(newAccount);
        console.log("Create Account:"+JSON.parse(b));
        helper.createAccount(component,newAccount);
	}
    
})

Helper Code​

({
	createAccount: function(component, acc) {
        var action = component.get("c.saveAccount");
        console.log(acc);
        action.setParams({
            "acc1": acc
            
        });
        action.setCallback(this, function(response){
            var state = response.getState();
            if (state === "SUCCESS") {
                var accounts = component.get("v.accounts");
                accounts.push(response.getReturnValue());
                component.set("v.accounts", accounts);
            }
        });
        $A.enqueueAction(action);
    }    
})

This Code is working only upto the page,but its not saving the the account when ever i click the create account button,but if i remove the force inputfield the account is getting created.
