VSCodeVim Normal Mode Key Bindings ^ Setting

I am using vscode with vim (by extension vscodevim), But some my setting in the vim is not work

"vim.normalModeKeyBindings": [
    {
        "before":["h","h"],
        "after":["^"]       
    }
]

But the insert mode is fine

"vim.insertModeKeyBindings": [
    {
        "before":["h","h"],
        "after":["<Esc>","^"]
    }
]

I want to Go to beginning of line by h+h

It work when insert mode but not in normal mode ? How to fix it ?
