title: extjs' passing extra parameters for grid due using pagination buttons
body: <p>I have a problem. I have <code>getAllJobsControllerUrl()</code> function which return url with specific parameters:</p>
  
  <pre><code>        proxy: new Ext.data.ScriptTagProxy({
                        url: getAllJobsControllerUrl(),
                        method : 'GET'
          })
  </code></pre>
  
  <p>And all code concerned with grid:</p>
  
  <pre><code>   var store = new Ext.data.JsonStore({
          root: 'jobs',
          totalProperty: 'totalCount',
          fields: [ 
  
                    {firld description}],
  
          proxy: new Ext.data.ScriptTagProxy({
                        url: getAllJobsControllerUrl(),
                        method : 'GET'
          })
      });
  
  
      var grid = new Ext.grid.GridPanel({
          id: 'mainGrid',
          el:'mainPageGrid',
          autoWidth: true,
          store:store,
          cm:cm,
          viewConfig:{
              forceFit:true
          },
          width :1000,
          height:500,
          loadMask:true,
          frame:false,
  
          bbar: new Ext.PagingToolbar({
              id : 'mainGridPaginator',
              store:store,
              pageSize:10,
              displayMsg: '{0} - {1} of {2} results',
              emptyMsg:'No results found for your search criterion',
              displayInfo:true
          }),
  
          tbar:tabBar
      });
  </code></pre>
  
  <p>The Question/Problem: When I make Ajax Request with getAllJobsControllerUrl() and then reload store, I'm sending to server proper request string.</p>
  
  <p>But when I'm trying to use pagination buttons ('&lt;-' and '->' in the bottom of grid), It seems I'm sending the request string which has been formed once on first access and then it don't modify.</p>

  <p>Added:</p>
  
  <pre><code>function getAllJobsControllerUrl() {
      return '../../statusList/getJobs/search-' + searchType + '-' + searchValue + 
              '/sort-' + sortName + '-' + sortOrder + 
              '/filterSd-' + filterSubmittedDate +
              '/filterSt-' + filterStatus +
              '/filterUn-' + filterUserName +
              '/filterJn-' + filterJobName
  }
  </code></pre>
