vue js ajax call cannot read property 'push' of undefined

I am having problems with vue.js when it comes to pushing data from the database to the webpage. I am using laravel 5.3 which converts data to Jason. the code posts to the server the number of records to be fetched then the server response with the data in which i want to display on the webpage. here is Vue js Code

new Vue({
        el: "#projects",
        data: {

            count: 0,
            fetched_projects: []
}

 methods:{
       checkproject: function(){
            var fetch = this.count += 4;               

           axios.post('/loadmore', {fetch: fetch })
               .then(function(response) {

                  this.fetched_projects.push(response.data);

               })
               .catch(function(error){
                   console.log(error);
               });

       }

HTML

 <div class="row">
    <div class="col-md-3">
        <ul v-for="more_projects in fetched_projects">
            <li>@{{ more_projects }}</li>

        </ul>

    </div>
</div>

Laravel controller

 public function setloadMore(Request $request){

  $new_projects = $request->fetch;

  $results = Model1::with('relation')->take($new_projects)->get();

  return $results;


}

The problem is on this.fetched_projects.push(response.data); its giving me "cannot read property 'push' of undifined"

you are having "this" problem, try defining something like var that = this where you have defined fetch, and use that in place of this inside the post it should work.

You'd want this to be your component, so use an arrow function:

 methods:{
   checkproject: function(){
        var fetch = this.count += 4;               

       axios.post('/loadmore', {fetch: fetch })
           .then(response => {
              this.fetched_projects.push(response.data);
           })
           .catch(function(error){
               console.log(error);
           });

   }
