Multiselector checkAll selects all options instead of filtered list

I am using multiselector and whenever I try to select all filtered result by clicking checkAll then it selects all options not only filter list but all.

Example: I have list like

abc1, abc2, abc3, xyz1, xyz2

and I filtered by “abc” text and I got three result abc1, abc2 and abc3

Then I clicked on checkAll link it shows it selected 3 options but it is selecting all 6 options, for this problem I have done general method and it is working fine

Added this function call in that html file

<script>

$(document).ready(function() {

checkAllCorrection(‘#selctboxid’);

});

</script>

General method in application.js file

function checkAllCorrection(fieldName){

$(fieldName).bind(“multiselectcheckall”, function(event, ui){

    var checkedValueList = [];

    $(fieldName).multiselect(“getChecked”).each(function(){

         checkedValueList.push(this.value);

     });

    $(fieldName).multiselect(“refresh”);

    $(fieldName).multiselect(‘widget’).find(“:checkbox”).each(

          function(){

               if(checkedValueList.indexOf(this.value) == -1

&& this.checked)        this.click();

           }

    );

    });

}
