Sapui5 table shows only the same record

in js

    <script>
        function getResults() {
            var radios = document.getElementsByName("address");    
            for (var i = 0; i < radios.length; i++) {       
                if (radios[i].checked) {
                var apost = radios[i].value
                     //send set state request
                $.ajax({
                    type: "POST",// here you can use get/post  if use get then in php use $_GET['a'] or use post then in php $_POST['a'] 

                    url: "your php file name with path",
                    data: {a:apost},
                    beforeSend: function () {



               },
                    success: function (data, textStatus, XmlHttpRequest) {
if(data==1)// see php file code you will know how i use data==1
{
    // do your action                
 }
else{
// in you php there is someyhing error
}
     },
                    error: function (XMLHttpRequest, textStatus, errorThrown) {

    // do you action
                   }
                });

                    break;
                }
            }
        </script>  

in PHP

   <?php

          mysql_connect("localhost", "tiger", "tiger") or die (mysql_error ());
          mysql_select_db("theaterdb") or die(mysql_error());
          $strSQL =("DELETE FROM theater WHERE theater_name='".$_POST["a"]."'");
          $rs = mysql_query($strSQL);
            echo 1;  // here i use 1 to get response if this is done successfully then in ajax we get 1 in data  
          mysql_close();

        ?>

I think that's because of the browser cache. try adding some hash like date.now() after image URL changes. for example:

setState({
   imageSrc: '...',
   imageHash: Date.now()
})

and in render:

render(){
  return(
      <img src={`${imageSrc}?${imageHash}`} />
  )
}
