angularjs - Proper angular syntax in haml -

i working on angular project haml views , have following code.

%textarea.answer{ |     placeholder: 'please enter answer', |     onfocus: '{ this.placeholder = " " }', |     ng: { |         model: 'canvasctrl.steptoshow.answer', |     } |                                                                                                                                      } | 

i wanted add model-options this:

%textarea.answer{ |     placeholder: 'please enter answer', |     onfocus: '{ this.placeholder = " " }', |     ng: { |         model: 'canvasctrl.steptoshow.answer', |         model-options: 'canvasctrl.savingsoptions', |     } |                                                                                                                                      } | 

i though following syntax error haml:

syntax error, unexpected tlabel ...ptoshow.answer', model-options: 'canvasctrl.savingsoptions',... ... ^ projects/canvas/views/home.haml:53: syntax error, unexpected ',', expecting tstring_dend ...s: 'canvasctrl.savingsoptions', } )}>\n \n \n \n

i tried following didn't work:

 ng: { |         model: {'canvasctrl.steptoshow.answer', options: 'canvasctrl.savingsoptions', } |  } |
