sencha test timeout, waiting

I'm starting with Sencha test and trying run some simple tests. I start with simple webpage and it works. Now when I create simple form i ext, and try to test it using localhost, I have communicate

Failed: Timeout waiting for target (input[name="name"]) to be available

I'm doing it exactly same way just change the elements names, so it should work. I know that it can be cos page loading is too long so I try add function for wait (both with time and until it find element), nothing helps.

Any ideas?
