[SalesForce] Unable to add row dynamically in vf page

I am beginner to salesforce. I want to add row dynamically to VF page when i clicked add row button.

this is my script

<apex:page standardController="Employee__c"  extensions="Cutomextension">
   <apex:form >
      <apex:pageBlock >
         <apex:pageBlockTable value="{!Employee__c}" var="emp">
            <apex:column headerValue=" Employee Name">
               <apex:inputField value="{!emp.name}"/>
            </apex:column>
         </apex:pageBlockTable>
         <apex:commandButton action="{!add}" value="Add Row"/>
      </apex:pageBlock>
   </apex:form>
</apex:page>

Controller:

public with sharing class Cutomextension {

    public Employee__c emp {get; set;}
    public List<Employee__c> empList {get; set;}
    public static Integer addCount {get; set;}

    public Cutomextension(ApexPages.StandardController controller) {
        this.emp = (Employee__c)Controller.getRecord();
        empList = new List<employee__c>();
    }

    public void add() {
        empList.add(new employee__c());
    }
}

When i clicked add row button, new row doesn't get added. Can anyone tell me what is wrong with my code.

As I understand you want to show a list of records in your page. Please read the following articles about showing a set of records in a pages and try to code it for your case.

Custom List Controller
Standard List Controller
dynamically add rows in visualforce page 1
dynamically add rows in visualforce page 2

If you have any further question after reading the articles above please add an update to this question.

[SalesForce] Manage State for apex:inputCheckbox on Visualforce page when adding dynamic apex:pageBlockTable rows

Wow, I don't know how to feel about this. The answer is, Don't use apex:inputCheckbox, always use apex:inputField when binding to a value on a controller. Apex will do the work of knowing it's a boolean and making it a checkbox.

Ouch, that was a bunch of time wasted.

Maybe someone could add this to the apex:inputCheckbox documentation, right after it says this: "Use this component to get user input for a controller method that does not correspond to a field on a Salesforce object." - to say, "If you're binding a checkbox to a controller, use apex:inputfield" and it will be rendered as a checkbox.

[SalesForce] Filter and search is not working

I see that the code where you find actual accounts is not returned in wrapper format

    public pagereference Search()
    {
        String finalSearchValue = '%' + fullname + '%';
        Accounts = [Select Id, Name, Active__c FROM Account
                    where Name like :finalSearchValue];
        wraplist = new list<wrapData>();  
        for(Account a: Accounts)
        {
            wrapList.add(new wrapData(a));
        }
       return null;
   }

Same way apply for filter method as well.
