Extjs4 grid's paging functionality is not working -


i working in extjs4. adding paging functionality grid. having grid view code as- allquestionpapers.js

ext.define('balaee.view.qb.qbqns.       ', {             extend : 'ext.grid.panel',             alias : 'widget.paperlist',             id : 'paperid',             store : 'qb.qbqnsstore',             border : false,             // height:autoheight,             width : 600,             autoscroll : true,             columns : [{                         text : 'date',                         width : 200,                         dataindex : 'createdate'                     }, {                         text : 'questionpaperno',                         width : 200,                         dataindex : 'questionpaperno'                     }, {                         text : 'marks',                         width : 200,                         dataindex : 'obtainmarks'                     }],             dockeditems : [{                         xtype : 'pagingtoolbar',                         id : 'pagingtoolbarid',                         pagesize : 10,                         dock : 'bottom',                         displayinfo : true                      }]         });

and in controller dynamically creating store , binding grid.for had written code as-

getallpapers:function()     {            var paperliststore=ext.create('balaee.store.qb.qbqnsstore',             {autoload: {params:{start:0, limit:10}}});         proxy= paperliststore.getproxy();         ext.apply(proxy.api,{             read:'index.php/questionbank/qbpaper/getuserallquestionpaper'         });           ext.apply(proxy.reader,{             type:'json',             root:'questions'         });          ext.apply(proxy.writer,{             type:'json',             root:'data'         });          var answers = '{"data":[';         answers = answers + '{"userid":1}';         answers =answers+']}';         console.log(answers);           paperliststore.load({             params:{                 data: answers             },             callback: function(records,operation,success){                 console.log(records);                 console.log("successfully data send");             },             scope:this         });          var temp2=ext.getcmp('qbqnsresultmainid');         temp2.removeall();          var worldchaptor1 =ext.create('balaee.view.qb.qbqns.allquestionpapers');         var resultview = ext.getcmp('pagingtoolbarid');         console.log(resultview);         resultview.bindstore(paperliststore);          temp2.add(worldchaptor1); }

all working correctly.but grid showing 3 records per page instead of showing 25 records per grid's paging function's dispaly message"displaying 1-25 of 280". changes need make in order diaplay such 25 record per page.
