Title: Fix issue with RegExp for getting context and replace context in blueprint

Fix issue with getting contex. Javascript always replace backslash.

Also fix issue with replace context parents in content. For example:
```
project[tasks_attributes][0][assigments_sttributes[new_assigments][file_name]
```
will be replaced to
```
project[tasks_attributes][0][assigments_sttributes[0][file_name]
```
and will replace first child object after post.
