I'm using the jqgrid but I want to show it by clicking a button, I mean if a select some paramaters it change the content of the grid, I have used a button with a onclick event that call the jqgrid but the problem is that it just works in the first time, if I want to change some parameter and show the jqgrid again it doesn't update the content. There is some way I can reload the url where I get the data by clicking a button??

There is the code I'm using:

$(function() {

function showGrid()
