title: Extjs- Grid column headers refresh for every search
body: <p>I am trying to sort my results grid based on a default column header every time the results gets displayed. I tried giving a sorter to the store and it worked fine when the page loads first time. Its working as I want it to be. But the problem arises only when I try to click on a different column header in the grid. When I click on a different header it sorts based on that particular column values. If I click on search button at this point of time without reloading the page, the search results get displayed and are sorted based on my previous selected column. I want this to be sorted based on the default column. Problem is the grid gets refreshed with search results every time I click on search or reset buttons but the column headers are not getting refreshed. So the results are getting sorted based on my previous selection. To fix this problem, I am trying to reload the whole page every time I click on search or reset. Is there a way that I can refresh the column headers along with the search results every time I click on the search so that the results get sorted based on the default column header. I am able to refresh the search results and the pagination part for every search but not the column headers. Any solution...</p>
  
  <p>Thanks....</p>
