Can you please help me in checkbox issue i am facing while migrating from 1.0.1 to 1.3

Here is the specific code for which the error is.

1. if ($('input:checkbox[name="checkboxMyChoice"+counter]:checked').val() == 1 );{
2.                     // do some logic
3.                 }

the error in console is this

unrecognized expression: input:checkbox[name= 

Please let me know what/how should I use it correctly to check the value.

Help very much appreciated
