Hello Yamini,
      You can call controller method on click of command button by using action attribute 
here is the code:
VF Component 
  
<apex:component controller="DemoController">
    <apex:form>
    	<apex:input label="Employee Name" value="{!emp.Name__c}" />
        <apex:input label="Employee company" value="{!emp.company__c}" />
        <apex:commandButton action="{!saveDetails}"/>
    </apex:form>
</apex:component>

Controller code:- 
public class DemoController {
    public Employee__c emp{get;set;}
    public void saveDetails(){
        insert emp;
    }
}

Hi,

You can call apex controller method from command button by following ways - 

1. You can use action attribute of command button to call apex controller method

For example -  
<!-- Page: -->
<apex:page controller="sampleController">
<apex:commandButton action="{!save}" value="Save" />
</apex:page>
  
//Apex Class
public with sharing class sampleController{
    public void save(){
    //Business logic
    }
}
2. You can use action function too. Visit this link for more details and example https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_compref_actionFunction.htm?search_text=apex:actionfunction

Hope you find this helpful.

Hello Yamini,
     
    You can controller method in diffrenet way
1 Using CommandButton with action attribute
    
    in action attribute specify your controller method like
    <apex:commanbutton value="XYZ" action="{!yourControllerMethod}"/>
2 Using action functon 
    
    <apex:commandButton  value="XYZ" onclick="callMethod()"/>
    <apex:actionFunction id="setState" action="{!yourControllerMethod}; return false;" name="callMethod" />
    using action fuction you can pass parameter to controller
3 Using action support
    
    </apex:outputpanel>
        <apex:outputText value="Enter Value"/>
        <apex:actionSupport event="onclick" action="{!yourControllerMethod}"/>
    </apex:outputpanel>
    
Thank you,
