Checkbox doesn't get checked in knockout

[OKHA]

I have a checkbox and click event for checkbox for updating data. When I click on the checkbox the data is updating but the checkbox does not get not checked. This is my html code:\[code\]<td> <input type="checkbox" data-bind="checked: status, disable: status, click: $root.UpdateStatus" /></td>\[/code\]This is my script:\[code\]self.UpdateStatus = function (tblUsers) { $.ajax({ type: "POST", url: 'SinglePageApp.aspx/UpdateStatus', data: "{statusVal: 'true',goalId: " + tblUsers.goalId + "}", contentType: "application/json; charset=utf-8", success: function (result) { alert(result.d); }, error: function (XMLHttpRequest, textStatus, errorThrown) { alert(textStatus); alert(errorThrown); } });};\[/code\]I want my checkbox to get checked when it is clicked. And after that put updated data after checkbox clicked.
