title: Issue with Extjs 3.2 grid paging not working
body: <p>I have multiple store on my page to load data in extjs grid. I am using a js function to load these store. Based on the search button click event I attach the respective store to the grid. Its working fine. In the load function I have lots of params that I need to send to the backend to fetch the results and show in the grid. Now with pagination in place. Is there anyway that I can add that js function call inside the paging so I can pass those params. Because right now if I click next button in paging nothing is getting returned. since the required parameters are missing to fetch the results. I tried all the given sample on internet but nothing is working. </p>
  
  <p>It would be great if somebody can actually post an example on paging passing parameters or calling js function on next button event.</p>
  
  <p>Any help will be really appreciated. Thank you.</p>
  
  <p>below is the load store function that I want to call on my next event on pagination.</p>
  
  <pre><code>function loadStore(prodId, productsName, doctype, criteria, filename, titlename) {
      store.removeAll();
      store.load({
          params: {
              // specify params for the first page load if using paging
              start: 0,
              limit: g_perPage,
              ajax: "true",
              productId: prodId,
              ProductsNameArr: productsName,
              assetsname: doctype,
              criterianame: criteria,
              newfilename: filename,
              newtitlename: titlename
          }
      });
  }
  </code></pre>
