Get variable from Sencha Touch Ext.data.JSONP.request response - html

Question

I'm trying to get a boolean (success) and a HTML string (result) from the response to an Ext.data.JsonP.request, but I can't fgure out how. Here's the code I have so far:
Ext.data.JsonP.request({
url: 'http://wereani.ml/shorten-app.php',
callbackKey: 'callback',
params: {
data: Ext.encode(values)
},
success: function(response) {
console.log(response);
console.log(JSON.stringify(values));
console.log('Link Shortened');
if(response.responseText['success'] == true) {
Ext.Msg.alert('Link Shortened', response.responseText, Ext.emptyFn);
} else {
Ext.Msg.alert('Error', response.responseText, Ext.emptyFn);
}
form.reset();
},
failure: function(response) {
console.log(response);
console.log(JSON.stringify(values));
console.log('Error');
Ext.Msg.alert('Error', 'Please try again.', Ext.emptyFn);
}
});
Some sample JSON-P:
callback({"success":false,"result":"<div class=\"error\">Please enter a valid link to shorten!<\/div>"})
The error I'm currently getting is Uncaught TypeError: Cannot read property 'success' of undefined.
Thanks in advance for the help!
EDIT: It seems that while response is Object {success: false, result: "<div class="error">Please enter a valid link to shorten!</div>"}, response.responseText is undefined. Am I using the wrong variable? I couldn't find any documentation on response.
EDIT 2: It seems that the reason Console.log(response.responseText) was returning undefined is because it.... was. The JsonP-encoded variables (success and result) that I passed were parsed automatically into the object, and response.responseText was never created (though I think it was supposed to be). The solution was to just read response.success and response.result directly!
ANSWER: Here's the code that worked. Thanks to Viswa for the help!
Ext.data.JsonP.request({
url: 'http://wereani.ml/shorten-app.php',
callbackKey: 'callback',
params: {
data: Ext.encode(values)
},
success: function(response) {
if(response.success === true) {
Ext.Msg.alert('Link Shortened', response.result, Ext.emptyFn);
} else {
Ext.Msg.alert('Error', response.result, Ext.emptyFn);
}
form.reset();
},
failure: function(response) {
console.log('Error');
Ext.Msg.alert('Error', '<div class="error">Please try again.</div>', Ext.emptyFn);
}
});

Try like this
Ext.data.JsonP.request({
url: 'http://example.com/script.php',
callbackKey: 'callback',
params: {
data: Ext.encode(values)
},
success : function(response) {
console.log("Spiffing, everything worked");
// success property
console.log(response.success);
// result property
console.log(response.result);
},
failure: function(response) {
console.log(response);
Ext.Msg.alert('Error', 'Please try again.', Ext.emptyFn);
}
});
